It is a noble metal and a member of the platinum group. [65][66], Niobium forms oxides in the oxidation states +5 (Nb2O5),[67] +4 (NbO2), +3 (Nb2O3),[53] and the rarer oxidation state, +2 (NbO). The chemical symbol for Silicon is Si. Antimony is a chemical element with atomic number 51 which means there are 51 protons and 51 electrons in the atomic structure. Praseodymium is the third member of the lanthanide series and is traditionally considered to be one of the rare-earth metals. This website was founded as a non-profit project, build entirely by a group of nuclear engineers. Very soft and malleable, indium has a melting point higher than sodium and gallium, but lower than lithium and tin. If you follow the configuration pattern, the electron configuration of ruthenium should be: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d6 5s2 or [Kr] 4d6 5s2. Terbium is a chemical element with atomic number 65 which means there are 65 protons and 65 electrons in the atomic structure. It is the fifth most abundant element in Earth’s crust and the third most abundant metal, after iron and aluminium. The chemical symbol for Dysprosium is Dy. [83], C-103 alloy was developed in the early 1960s jointly by the Wah Chang Corporation and Boeing Co. DuPont, Union Carbide Corp., General Electric Co. and several other companies were developing Nb-base alloys simultaneously, largely driven by the Cold War and Space Race. [87] For example, the Large Hadron Collider uses 600 tons of superconducting strands, while the International Thermonuclear Experimental Reactor uses an estimated 600 tonnes of Nb3Sn strands and 250 tonnes of NbTi strands. Like the other metals of the platinum group, ruthenium is inert to most other chemicals.
