platinum electron configuration

Similarly, adding electrons results in a negative oxidation state. Antimony is a chemical element with atomic number 51 which means there are 51 protons and 51 electrons in the atomic structure. Tellurium is a brittle, mildly toxic, rare, silver-white metalloid. A freshly exposed surface of pure copper has a reddish-orange color. Discoverer: Davy, Sir H. and Thénard, L.-J. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. Tellurium is a chemical element with atomic number 52 which means there are 52 protons and 52 electrons in the atomic structure. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. The chemical symbol for Niobium is Nb. In the periodic table, potassium is one of the alkali metals. Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding lighter elements with charged particles. The chemical symbol for Helium is He. Platinum does oxidize, forming PtO2, at 500 °C; this oxide can be easily removed thermally. Molybdenum is a chemical element with atomic number 42 which means there are 42 protons and 42 electrons in the atomic structure. Oxidation states are typically represented by integers which may be positive, zero, or negative. The chemical symbol for Fermium is Fm. Actinium is a soft, silvery-white radioactive metal. The chemical symbol for Beryllium is Be. Natural boron consists primarily of two stable isotopes, 11B (80.1%) and 10B (19.9%). Bismuth is a chemical element with atomic number 83 which means there are 83 protons and 83 electrons in the atomic structure. The most common oxidation states of platinum are +2 and +4. Chlorine is a yellow-green gas at room temperature. Sodium is a soft, silvery-white, highly reactive metal. Our Website follows all legal requirements to protect your privacy. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. 8, 50 (1964)", "Seventy-fifth Anniversary of the Discovery of the Platiniferous Merensky Reef", 10.1002/0471238961.1612012019052513.a01.pub2, "Evidence of huge deposits of platinum in State", "Identification of meteoritic components in imactites", "Effects of relativistic motion of electrons on the chemistry of gold and platinum", "Synthetic metallomolecules as agents for the control of DNA structure", "Sur les métaux égyptiens: Présence du platine parmi les caractères d'inscriptions hiéroglyphiques, confié à mon examn", "Ancient Platinum Technology in South America: Its use by the Indians in Pre-Hispanic Times", "Several Papers concerning a New Semi-Metal, Called Platina; Communicated to the Royal Society by Mr. Wm. Bromine is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Caesium is a chemical element with atomic number 55 which means there are 55 protons and 55 electrons in the atomic structure. Titanium can be used in surface condensers. The chemical symbol for Iridium is Ir. The chemical symbol for Einsteinium is Es. The chemical symbol for Tin is Sn. Chabaneau succeeded in removing various impurities from the ore, including gold, mercury, lead, copper, and iron. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element. If you continue to use this site we will assume that you are happy with it. Platinum is one of the least reactive metals. The electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. Platinum(II) and platinum(IV) bromides are known as well. The chemical symbol for Cerium is Ce. The chemical symbol for Berkelium is Bk. [80] Some products, such as blenders and vehicles, with a silvery-white color are identified as "platinum". Californium is a chemical element with atomic number 98 which means there are 98 protons and 98 electrons in the atomic structure. Neptunium is a chemical element with atomic number 93 which means there are 93 protons and 93 electrons in the atomic structure. [17], Cisplatin, or cis-diamminedichloroplatinum(II) is the first of a series of square planar platinum(II)-containing chemotherapy drugs. It readily forms hard, stable carbides in alloys, and for this reason most of world production of the element (about 80%) is used in steel alloys, including high-strength alloys and superalloys. [24], In 1865, chromites were identified in the Bushveld region of South Africa, followed by the discovery of platinum in 1906. Plutonium is a chemical element with atomic number 94 which means there are 94 protons and 94 electrons in the atomic structure.
