    Tantalum (Ta) | AMERICAN ELEMENTS

    Tantalum is found in the minerals tantalite, microlite, wodginite, euxenite, and polycrase. Tantalum was first discovered by Anders G. Ekeberg in 1802 in Uppsala, Sweden. Due to the close relation of tantalum to niobium in the periodic table, Tantalum's name originates from the Greek word Tantalos, meaning Father of Niobe in Greek mythology.

    NIOBIUM AND TANTALUM NIOBIUM Niobium is a soft silverygrey metal that resembles freshcut steel. It neither tarnishes nor oxidizes in air at room temperature because of a thin coating of niobium oxide. It does readily oxidize at high temperatures (above 200ºC), particularly with oxygen and halogens. Niobium is not attacked by cold acids but

    Vanadium, Niobium and Tantalum ScienceDirect

    Niobium and tantalum provide no counterpart to the cationic chemistry of vanadium in the +3 and +2 oxidation states. Instead, they form a series of "cluster" compounds based on octahedral M 6 X 12 units. The occurrence of such compounds is largely a consequence of the strength of metalmetal bonding in this part of the periodic table (as reflected in high enthalpies of atomization), and ...
