Abstract:Using the new developed one-atom-state method of pure metals, the electronic structures of the outer shell electrons of V, Nb and Ta metals have been analyzed systematically, and been determined to be (4sf)0.27(4sc)1.24(3dc)3.49, (5sf)0.32(5sc)0.39(4dc)4.29 and (6sf)
(6sc)0.17(5dc)4.40, respectively. The bond length and strength of these metals have also been determined. The conductivity of V, Nb and Ta metals discussed qualitatively and relative magnitude of resistivity were well explained.
