There's considerable variation in the arrangement of these dots in Lewis diagrams. Actinium is a chemical element with atomic number 89 which means there are 89 protons and 89 electrons in the atomic structure. Erbium is a silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements. Promethium is one of only two such elements that are followed in the periodic table by elements with stable forms. Gold is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. This database focuses on the most common chemical compounds used in the home and industry. Einsteinium is the seventh transuranic element, and an actinide. The chemical symbol for Neptunium is Np. Q. Osmium is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Titanium is a lustrous transition metal with a silver color, low density, and high strength. A colorless, odorless, tasteless noble gas, krypton occurs in trace amounts in the atmosphere and is often used with other rare gases in fluorescent lamps. Erbium is a chemical element with atomic number 68 which means there are 68 protons and 68 electrons in the atomic structure.
