Each entry has a full citation identifying its source. Use the element blocks of the periodic table to find the highest electron orbital. This is due to the presence of f orbitals. [46][47], The metal was used by pre-Columbian Americans near modern-day Esmeraldas, Ecuador to produce artifacts of a white gold-platinum alloy. Nonbonding Electron Definition. 0% average accuracy. [31], Hexachloroplatinic acid mentioned above is probably the most important platinum compound, as it serves as the precursor for many other platinum compounds. PtAs2), and as end alloys with nickel or copper. By itself, it has various applications in photography, zinc etchings, indelible ink, plating, mirrors, porcelain coloring, and as a catalyst. The resistance wire in the thermometer is made of pure platinum (e.g. Who was the man seen in fur storming U.S. Capitol? Dichloro(cycloocta-1,5-diene)platinum(II) is a commercially available olefin complex, which contains easily displaceable cod ligands ("cod" being an abbreviation of 1,5-cyclooctadiene). [78], Platinum's rarity as a metal has caused advertisers to associate it with exclusivity and wealth. Find the amount mass of 49 mass% NaSO4 solution to be added to 172 g of water to get 2 mass% solution of this salt. The frame of the Crown of Queen Elizabeth The Queen Mother, manufactured for her coronation as Consort of King George VI, is made of platinum. [30], Platinum exists in higher abundances on the Moon and in meteorites. Platinum arsenide, sperrylite (PtAs2), is a major source of platinum associated with nickel ores in the Sudbury Basin deposit in Ontario, Canada. An atom of Platinum in the gas phase, for example, gives off energy when it gains an electron to form an ion of Platinum. This Site Might Help You. Some transition metals, including Platinum, Chromium, and Tungsten, have electron configurations in which the s electron is transferred to the d orbitals. It has been employed as a catalyst since the early 19th century, when platinum powder was used to catalyze the ignition of hydrogen. 188Pt, 191Pt, and 193Pt decay primarily by electron capture. The most common oxidation states of platinum are +2 and +4. Platinum does oxidize, forming PtO2, at 500 °C; this oxide can be easily removed thermally. Another large alluvial deposit is in the Ural Mountains, Russia, and it is still mined. Save. The origin of the name comes from the Spanish word platina meaning silver. [Xe] 6s1 4f14 5d9 Platinum should be a s2 d8 compound like nickel. He succeeded in making malleable platinum by alloying it with gold, dissolving the alloy in hot aqua regia, precipitating the platinum with ammonium chloride, igniting the ammonium chloroplatinate, and hammering the resulting finely divided platinum to make it cohere. These two impurities are thus removed by running an electromagnet over the mixture. Platinum hexafluoride is a strong oxidizer capable of oxidizing oxygen. What we will do now is place those electrons into an arrangement around the nucleus that indicates their energy and the shape of the orbital in which they are located. Platinum also has 34 synthetic isotopes ranging in atomic mass from 165 to 204, making the total number of known isotopes 40. For other uses, see, CRC press encyclopedia of materials and finishes, 2nd edition, Mel Schwartz, 2002, Materials handbook, fifteenth edition, McGraw-Hill, by John Vaccari, 2002, Kelly, Thomas D. and Matos, Grecia R.

C. Chaston, Platinum Metals Rev. Its name is derived from the Spanish term platino, meaning "little silver". There are 118 elements in the periodic table. [58], If pure platinum is found in placer deposits or other ores, it is isolated from them by various methods of subtracting impurities. An electron configuration can quickly and simply tell a reader how many electron orbitals an atom has as well as the number of electrons populating each of its orbitals. The mine ceased operations in 1990. At Platinum, Alaska, about 17,000 kg (550,000 ozt) was mined between 1927 and 1975. Platinum is insoluble in hydrochloric and nitric acid, but dissolves in hot aqua regia (A mixture of nitric and hydrochloric acids), to form chloroplatinic acid, H2PtCl6.[14]. The ground state electron configuration of ground state gaseous neutral platinum is [Xe].4f 14.5d 9.6s 1 and the term symbol is 3 … Melting point The temperature at which the solid–liquid phase change occurs. The least stable of these are 165Pt and 166Pt, with half-lives of 260 µs, whereas the most stable is 193Pt with a half-life of 50 years. He worked with the platinum by fusing it with arsenic, then later volatilizing the arsenic. Platinum is a chemical element with the symbol Pt and atomic number 78. Principal Energy Level Definition . [52] From their first encounters with platinum, the Spanish generally saw the metal as a kind of impurity in gold, and it was treated as such. I am a retired engineer. Boiling point The temperature at which the liquid–gas phase change occurs. If you don’t have a chart, you can still find the electron configuration. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. In the Sudbury Basin, the huge quantities of nickel ore processed make up for the fact platinum is present as only 0.5 ppm in the ore. So let's make the electron configuration for that 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d9 from here on out anytime you see d9 we're going to change it. The Madelung … [66], From 1889 to 1960, the meter was defined as the length of a platinum-iridium (90:10) alloy bar, known as the international prototype of the meter. Still have questions? In the 18th century, platinum's rarity made King Louis XV of France declare it the only metal fit for a king. Edit. … [8], Pure platinum is a lustrous, ductile, and malleable, silver-white metal. Potassium hexachloroplatinate is similarly insoluble, and hexachloroplatinic acid has been used in the determination of potassium ions by gravimetry. However, some also write it as $\ce{[Xe] 4f^14 5d^8 6s^2}$. An electron configuration is the arrangement of electrons within an atom. The cod complex and the halides are convenient starting points to platinum chemistry. Platinum is paramagnetic, whereas nickel and iron are both ferromagnetic. [32] Platinum also strongly catalyzes the decomposition of hydrogen peroxide into water and oxygen[64] and it is used in fuel cells[65] as a catalyst for the reduction of oxygen. Here is a summary of the types of orbitals and how many electrons each can contain: So based on what we know about the quantum numbers and using the char… [23] The rare sulfide mineral cooperite, (Pt,Pd,Ni)S, contains platinum along with palladium and nickel. In 1741, Charles Wood,[53] a British metallurgist, found various samples of Colombian platinum in Jamaica, which he sent to William Brownrigg for further investigation. During electrorefining of copper, noble metals such as silver, gold and the platinum-group metals as well as selenium and tellurium settle to the bottom of the cell as "anode mud", which forms the starting point for the extraction of the platinum-group metals. Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. [79] "Platinum awards" are the second highest possible, ranking above "gold", "silver" and "bronze", but below diamond. [21][22] It is sometimes mistaken for silver. This decides the electron capacity of the shells. This started what is known as the "platinum age" in Spain. RE: electron configuration of platinum 2+electron configuration of platinum 2+? The subshells have a distinct shape and configuration, in which the electrons move freely. What is the moleclular fomula for hydro-dioxygen ? do you mean by saying oxidation number for atoms that have electron configuration? Although gold is also used in industrial applications, especially in electronics due to its use as a conductor, its demand is not so driven by industrial uses. Platinum atoms have 78 electrons and the shell structure is 2.8.18.32.17.1. For example, it appears that the most stable configuration for atoms of chromium, copper, niobium, molybdenum, ruthenium, rhodium, silver, platinum and gold involves only moving one electron into an s orbital. Palladium can be said to be doubly anomalous. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Some textbooks write the electron configuration for platinum (Pt) as $\ce{[Xe] 4f^14 5d^9 6s^1}$. Using the Russel-Saunders coupling for atoms you will find all the terms for platinum energy levels. [33], When hexachloroplatinic acid is heated, it decomposes through platinum(IV) chloride and platinum(II) chloride to elemental platinum, although the reactions do not occur stepwise:[34]. [52], Because the other platinum-family members were not discovered yet (platinum was the first in the list), Scheffer and Sickingen made the false assumption that due to its hardness—which is slightly more than for pure iron—platinum would be a relatively non-pliable material, even brittle at times, when in fact its ductility and malleability are close to that of gold. Also, some metal ions display colors that are similar to each other making it hard to tell them apart. The maximum electrons that can be carried by the sub-shell S is 2, by P is 6, by D is 10, and the F sub-shell can carry 14. [18], Platinum has six naturally occurring isotopes: 190Pt, 192Pt, 194Pt, 195Pt, 196Pt, and 198Pt. Platinum readily reacts with carbon. Primarily, the flame test detects the presence of metalions in a compound, and as ions of each element have a specific characteristicbased in their emission spectrum, the flame test for every element is differentand distinctive. This article is about the chemical element. Image explanation. Franz Karl Achard made the first platinum crucible in 1784. The previous bar was made of platinum in 1799. This gives two electrons in an s subshell, six electrons in a p subshell, ten electrons in a d subshell and fourteen electrons in an f subshell. Source(s): https://shorte.im/a976A. platinum have two oxidation states, +2 and +4. The electronic configuration of a lithium atom is 1s 2 2s, which indicates there are two electrons in the 1s sublevel and one electron in the 2s energy sublevel. Our platinum page has over 260 facts that span 87 different quantities. see PT cell for element K...not P: 32 At STP, which element is malleable and a good conductor of electricity? Platinum is also used in the petroleum industry as a catalyst in a number of separate processes, but especially in catalytic reforming of straight-run naphthas into higher-octane gasoline that becomes rich in aromatic compounds. Our platinum page has over 260 facts that span 87 different quantities. Platinum(II) and platinum(IV) bromides are known as well. [48] To work the metal, they would combine gold and platinum powders by sintering. Electronic Configurations Intro Last updated; Save as PDF Page ID 55229; Contributors and Attributions; The electron configuration of an atom is the representation of the arrangement of electrons distributed among the orbital shells and subshells. Finally, platinum is resistant to hydrochloric and sulfuric acids, whereas other substances are readily attacked by them. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Certain non-metals, including phosphorus, silicon and sulfur also combine with platinum. [10][11] The metal has excellent resistance to corrosion, is stable at high temperatures and has stable electrical properties. [40] The negative oxidation states exhibited by platinum are unusual for metallic elements, and they are attributed to the relativistic stabilization of the 6s orbitals. 190Pt is the least abundant at only 0.01%. PtO2, also known as Adams' catalyst, is used as a hydrogenation catalyst, specifically for vegetable oils. Platinum is often found chemically uncombined as native platinum and as alloy with the other platinum-group metals and iron mostly. Because platinum has a higher melting point than most other substances, many impurities can be burned or melted away without melting the platinum. Electronic configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 10 5s 2 5p 6 4f 14 5d 9 6s 1 >> Back to key information about the elementBack to key information about the element But i am really stumpted on this problem. What is Electron Configuration? Electron Configuration Chart. His historical account of the expedition included a description of platinum as being neither separable nor calcinable. a few seconds ago by. The specific layer he found, named the Merensky Reef, contains around 75% of the world's known platinum. [32], Treatment of hexachloroplatinic acid with an ammonium salt, such as ammonium chloride, gives ammonium hexachloroplatinate,[16] which is relatively insoluble in ammonium solutions. The Food and Drug Administration and other institutions have reviewed the issue and found no evidence to suggest toxicity in vivo. [clarification needed] Other chemists across Europe soon began studying platinum, including Andreas Sigismund Marggraf,[55] Torbern Bergman, Jöns Jakob Berzelius, William Lewis, and Pierre Macquer. [35] PtO2 and the less common PtO both decompose upon heating. 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d9 6s1 Or: [Xe] 4f14 5d9 6s1 There is a major exception to the normal order of electron configuration at Cr (#24) and Cu (#29). Think […] We know that Pd has 46 electrons by looking at the periodic table, and we know that "s" orbitals can have a maximum of 2 electrons, "p" can have 6, "d" can have 10, and "f" can have 14. Quiz. [7], As of 2021, the value of platinum is around $36.00 per gram ($1,120 per troy ounce). [28] In 2010, South Africa was the top producer of platinum, with an almost 77% share, followed by Russia at 13%; world production in 2010 was 192,000 kg (423,000 lb). For more info, I invite you to visit http://forums.studentdoctor.net/showthread.php?t=5... can someone explain electron configuration of platinum? [39], Zeise's salt, containing an ethylene ligand, was one of the first organometallic compounds discovered. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production. Their assumptions could not be avoided because the platinum they experimented with was highly contaminated with minute amounts of platinum-family elements such as osmium and iridium, amongst others, which embrittled the platinum alloy.

In 1752, Henrik Scheffer published a detailed scientific description of the metal, which he referred to as "white gold", including an account of how he succeeded in fusing platinum ore with the aid of arsenic. However, as you go up the energy levels of electron states, the s and d get closer together in energy, so the half filled orbital rule breaks down, making a 6s1 5d9 state rather than a 6s2 5d8. Platinum Electronic configuration. Interactive periodic table showing names, electrons, and oxidation states. Correspondingly, platinum is found in slightly higher abundances at sites of bolide impact on Earth that are associated with resulting post-impact volcanism, and can be mined economically; the Sudbury Basin is one such example. As is expected, tetracoordinate platinum(II) compounds tend to adopt 16-electron square planar geometries. The remaining 28.9 tonnes went to various other minor applications, such as medicine and biomedicine, glassmaking equipment, investment, electrodes, anticancer drugs, oxygen sensors, spark plugs and turbine engines. Ulloa also anticipated the discovery of platinum mines. 4 years ago. Being a heavy metal, it leads to health problems upon exposure to its salts; but due to its corrosion resistance, metallic platinum has not been linked to adverse health effects. [13] It is also attacked by chlorine, bromine, iodine, and sulfur. It is the only stable isotope with a non-zero spin; with a spin of 1/2, 195Pt satellite peaks are often observed in 1H and 31P NMR spectroscopy (i.e., Pt-phosphine and Pt-alkyl complexes). For example, the electron configuration of sodium is 1s 2 2s 2 2p 6 3s 1. Platinum is a chemically stable element as it is one of the least reactive metals (Nobel metal). Sublimation The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Antonio de Ulloa returned to Spain and established the first mineralogy lab in Spain and was the first to systematically study platinum, which was in 1748. Ammonium chloroplatinate can be converted to platinum by heating. Its physical characteristics and chemical stability make it useful for industrial applications. There are four kinds of electron configurations: s, p, d, and f orbitals. Platinum is a chemical element with the symbol Pt and atomic number 78. Unfortunately, since these are special cases, you will have to memorise (or be aware of) these elements when completing electron configurations. )[43][44], Dichloro(cycloocta-1,5-diene)platinum(II), Archaeologists have discovered traces of platinum in the gold used in ancient Egyptian burials as early as 1200 BC.
