Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in zinc ores and in bauxite. Silver is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Chromium is a steely-grey, lustrous, hard and brittle metal4 which takes a high polish, resists tarnishing, and has a high melting point. So the full electron configuration for Palladium would start with: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 Then you get to the critical point of deciding whether to fill it in as (4d 8, 5s 2) or (4d 10). Remember, the f orbital has to included before the d orbital because bismuth is after the lanthanide series.

Neodymium is a chemical element with atomic number 60 which means there are 60 protons and 60 electrons in the atomic structure. It is the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities. For example, carbon has nine possible integer oxidation states from −4 to +4. In writing the electron configuration for fluorine the first two electrons will go in the 1s orbital. Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars. In writing the electron configuration for nitrogen the first two electrons will go in the 1s orbital. Bismuth is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. Francium is the second-least electronegative element, behind only caesium, and is the second rarest naturally occurring element (after astatine). Platinum is used in jewelry, wire, to make crucibles and vessels for laboratory work, electrical contacts, thermocouples, for coating items that must be exposed to high temperatures for long periods of time or must resist corrosion, and in dentistry. Electron Configuration [Xe]6s 1 4f 14 5d 9. Osmium is a chemical element with the symbol Os and atomic number 76. Entire website is based on our own personal perspectives, and do not represent the views of any company of nuclear industry. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. The chemical symbol for Plutonium is Pu. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas.
