Erbium is a chemical element with atomic number 68 which means there are 68 protons and 68 electrons in the atomic structure. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In nuclear reactors, promethium equilibrium exists in power operation. Its properties are thus intermediate between those of chlorine and iodine. Platinum is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. 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. The chemical symbol for Actinium is Ac. It is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Discoverer: McMillan, Edwin M. and Abelson, Philip H.
