Element Niobium
The chemistry of niobium and its compounds.
Niobium - chemical symbol Nb, atomic number 41 - is a silvery-white, ductile, crystallizing in cubic centered lattice, well malleable, compressible and draggable, very resistant, chemical element from the group of transition metals (Group 5, vanadium group).
The transition metal occurs mainly in its standard compounds in the state +5, although any oxidation state of -1 to +5 are known. Significantly, the smaller oxidation states are found in compounds in which Nb-Nb bonds occur.
Biological functions of niobium are not known.
The following list includes online available information resources on the chemistry and physics of niobium and niobium compounds.
