[79] "Platinum awards" are the second highest possible, ranking above "gold", "silver" and "bronze", but below diamond. The NIST manufactured the wires from platinum bar stock with a chemical purity of 99.999% by weight). [Xe] 6s1 4f14 5d9 Platinum should be a s2 d8 compound like nickel. The cod complex and the halides are convenient starting points to platinum chemistry. )[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. An atom's electron configuration is a numeric representation of its electron orbitals. Nonbonding Electron Definition. Okay so anytime that it ends in d9 we're going to fix it up a little bit, same exact way we're going to take an electron from the 4s and we're going to move it over to the 3d. Watson F. R.

It turns out that the energy the electron configuration that is half-filled, 4s 1 3d 5, and filled orbital, 4s 1 3d 10, has lower energy than the typical filling order, 4s 2 3d 4, and 4s 2 3d 9.This pattern is followed in the 5 th row with Mo (#42) and Ag (#47). For example, a small box from burial of Shepenupet II was found to be decorated with gold-platinum hieroglyphics. Also, some metal ions display colors that are similar to each other making it hard to tell them apart. According to the older shell atomic model, electrons occupy several levels from the first shell nearest the nucleus, K, through the seventh shell, Q, farthest from the nucleus.In terms of a more refined, quantum-mechanical model, the K–Q shells are … Platinum Electronic configuration. Principal Energy Level Definition . Platinum atoms have 78 electrons and the shell structure is 2.8.18.32.17.1. Most platinum isotopes decay by some combination of beta decay and alpha decay. Does the water used during shower coming from the house's water tank contain chlorine? Since the list is long I won’t be able to provide explanation to all though u may find explanation for copper and chromium in my answer to question : answer to Why does 4s1 come after 3d5 in chromium ion's electronic configuration? Platinum finds use in jewellery, usually as a 90–95% alloy, due to its inertness. [19], Platinum is an extremely rare metal,[20] occurring at a concentration of only 0.005 ppm in Earth's crust. 5 years ago. However, the standard notation often yields lengthy electron configurations (especially for elements having a relatively large atomic number). 1s 2 2s 2 2p 6 3s 2 Preview this quiz on Quizizz. 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 … [58], If pure platinum is found in placer deposits or other ores, it is isolated from them by various methods of subtracting impurities. Boiling point The temperature at which the liquid–gas phase change occurs. 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… [39], Zeise's salt, containing an ethylene ligand, was one of the first organometallic compounds discovered. [6] Compounds containing platinum, such as cisplatin, oxaliplatin and carboplatin, are applied in chemotherapy against certain types of cancer. Unfortunately, since these are special cases, you will have to memorise (or be aware of) these elements when completing electron configurations. In this case the 5d orbital is shielded better by the full 4f orbital in Pt, so it is lower energy than the 6s orbital. 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. Electron configuration The arrangements of electrons above the last (closed shell) noble gas. For example, the electron configuration of sodium is 1s 2 2s 2 2p 6 3s 1. Therefore the electronic configuration of Platinum +2 ion = [Xe] 4f14 5d8 = 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d8. There is a major exception to the normal order of electron configuration at Cr (#24) and Cu (#29). Chemistry. 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. [17], In 2007, Gerhard Ertl won the Nobel Prize in Chemistry for determining the detailed molecular mechanisms of the catalytic oxidation of carbon monoxide over platinum (catalytic converter). N2+ 3H2→2NH3How many grams of hydrogen, H2, are necessary to react completely with 50.0g of nitrogen, N2? It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. What is the moleclular fomula for hydro-dioxygen ? After publishing the report in 1748, Ulloa did not continue to investigate the new metal. For example, in the United States, a musical album that has sold more than 1 million copies will be credited as "platinum", whereas an album that has sold more than 10 million copies will be certified as "diamond". Who was the man seen in fur storming U.S. Capitol? 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. Its name is derived from the Spanish term platino, meaning "little silver". This led to inconsistent results in his experiments. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity.[5]. An electron configuration is the arrangement of electrons within an atom. Example: Helium 2. All three reactions are reversible. Our platinum page has over 260 facts that span 87 different quantities. electron configuration … RE: electron configuration of platinum 2+electron configuration of platinum 2+? Electron configurations are based primarily on three principles: the Aufbau principle, the Pauli exclusion principle, and the Heisenberg uncertainty principle. sueellen_trejo_22790. Still have questions? 188Pt, 191Pt, and 193Pt decay primarily by electron capture. Platinum(IV) oxide, PtO2, also known as 'Adams' catalyst', is a black powder that is soluble in potassium hydroxide (KOH) solutions and concentrated acids. 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. a few seconds ago by. 1s 2. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition 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. [12] It reacts vigorously with fluorine at 500 °C (932 °F) to form platinum tetrafluoride. The current OSHA standard is 2 micrograms per cubic meter of air averaged over an 8-hour work shift. The +1 and +3 oxidation states are less common, and are often stabilized by metal bonding in bimetallic (or polymetallic) species. Electronic configuration: [Xe] 4f 14 5d 9 6s 1: Formal oxidation number: +2 +4: Electronegativities: 2.2: Atomic radius / pm: 137.3: Relative atomic mass: 195.084(9) Platinum was discovered by Julius Caesar Scaliger (IT) in 1557. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. 9th grade . [31], Hexachloroplatinic acid mentioned above is probably the most important platinum compound, as it serves as the precursor for many other platinum compounds. Our platinum page has over 260 facts that span 87 different quantities. [52], Platinum, along with the rest of the platinum-group metals, is obtained commercially as a by-product from nickel and copper mining and processing. [7], As of 2021, the value of platinum is around $36.00 per gram ($1,120 per troy ounce). ), the possibility that platinum could enter the body and cause adverse effects has merited study. The electron configuration of an element describes how electrons are distributed in its atomic orbitals. The most important thing to remember is that electrons fill orbitals from lowest energy to highest energy. Example: Chlorine 17. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. [21][22] It is sometimes mistaken for silver. Platinum is a chemical element with the symbol Pt and atomic number 78. Because it occurs naturally in the alluvial sands of various rivers, it was first used by pre-Columbian South American natives to produce artifacts. Most often the native platinum is found in secondary deposits in alluvial deposits. [51], In 1735, Antonio de Ulloa and Jorge Juan y Santacilia saw Native Americans mining platinum while the Spaniards were travelling through Colombia and Peru for eight years. 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 [35] PtO2 and the less common PtO both decompose upon heating. Ulloa and Juan found mines with the whitish metal nuggets and took them home to Spain. [82] The National Institute for Occupational Safety and Health has set a recommended exposure limit (REL) for platinum as 1 mg/m3 over an 8-hour workday.[83]. Platinum hexafluoride is a strong oxidizer capable of oxidizing oxygen. You are free: to share – to copy, distribute and transmit the work; to remix – to adapt the work; Under the following conditions: attribution – You must give appropriate credit, provide a link to the license, and indicate if changes were made. Some textbooks write the electron configuration for platinum (Pt) as $\ce{[Xe] 4f^14 5d^9 6s^1}$. Platinum is used as an alloying agent for various metal products, including fine wires, noncorrosive laboratory containers, medical instruments, dental prostheses, electrical contacts, and thermocouples. Although elemental platinum is generally unreactive, it dissolves in hot aqua regia to give aqueous chloroplatinic acid (H2PtCl6):[16], As a soft acid, platinum has a great affinity for sulfur, such as on dimethyl sulfoxide (DMSO); numerous DMSO complexes have been reported and care should be taken in the choice of reaction solvent. 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. It is used for this purpose for its prestige and inherent bullion value. Source(s): https://shorte.im/a976A. For the best answers, search on this site https://shorturl.im/axPUK. [56], In 1786, Charles III of Spain provided a library and laboratory to Pierre-François Chabaneau to aid in his research of platinum. [17] The use of platinum(II) acetylacetonate has also been reported. Scheffer described platinum as being less pliable than gold, but with similar resistance to corrosion. Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. The composition of a compound with molar mass 93 g/mol has been measured as:. Its physical characteristics and chemical stability make it useful for industrial applications. Continue Reading. 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. spontaneous combustion - how does it work? [81], According to the Centers for Disease Control and Prevention, short-term exposure to platinum salts may cause irritation of the eyes, nose, and throat, and long-term exposure may cause both respiratory and skin allergies. [41] Others include carboplatin and oxaliplatin. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use. Coins, bars, and ingots are traded or collected. [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. He worked with the platinum by fusing it with arsenic, then later volatilizing the arsenic. 0 0. Periodic Table Exceptions To Know. [23] The rare sulfide mineral cooperite, (Pt,Pd,Ni)S, contains platinum along with palladium and nickel. [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. GOP delegate films himself breaking into Capitol. The real answer comes from relativistic effects, electron correlation, and shielding effects. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence. Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence. ? Palladium can be said to be doubly anomalous. [48] To work the metal, they would combine gold and platinum powders by sintering. In the 18th century, platinum's rarity made King Louis XV of France declare it the only metal fit for a king. 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. Areas covered include atomic structure, physical properties, atomic interaction, thermodynamics, identification, atomic size, crystal structure, history, abundances, and nomenclature.

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. [52], Carl von Sickingen researched platinum extensively in 1772. Sometimes the metal was entirely incombustible, but when alloyed with osmium, it would volatilize. It was referenced in European writings as early as 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in 1748 that it began to be investigated by scientists. [63], The most common use of platinum is as a catalyst in chemical reactions, often as platinum black. Consequently, platinum is often found chemically uncombined as native platinum. [3][4], Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements.
