Discovered in 1802 by Ekeberg, but many chemists thought niobiumand tantalum were identical elements until Rowe in 1844, and Marignac, in 1866, showed that niobic and tantalic acids were two different acids. M4 1793. Electronegativity of Tantalum is 1.5. The tantalum atom has a radius of 143.pm and its Van der Waals radius is 200.pm. Corrections? However, a small amount, 0.012 percent, is tantalum-180, which has the unusual property of being found in its excited state. Apart from the Hydrochloric acid, this metal shows excellent resistance to all acids in normal temperature. Tantalum is separated from niobium compounds by solvent extraction in a liquid-liquid process and is then reduced to metallic tantalum powder. If you don’t have a chart, you can still find the electron configuration. Use the element blocks of the periodic table to find the highest electron orbital. The chemical symbol for Tantalum is Ta.

Tantalum is a Block D, Group 5, Period 6 element. Tantalum is chemically much like niobium because both have similar electronic configurations and because the radius of the tantalum ion is nearly the same as that of niobium as a result of the lanthanoid contraction. Omissions? O1 71. Although some of the impure metal was isolated earlier, the Russian chemist Werner Bolton prepared (1903) the first ductile tantalum, which was used briefly as incandescent lamp-filament material.
