Respuesta :

The electronic configuration of vanadium can be written as, [Ar] 3d³ 4s²

as the neutral atom of vanadium is Argon.

The chemical element vanadium has the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer somewhat stabilizes the free metal against further oxidation. Electron configuration is the arrangement of electrons in atomic orbitals. It shows the electrons in numbers, It doesn’t show the details on the spin of electrons like the orbital diagram. Electronic configuration of the Vanadium atom in ascending order of orbital energies,

         1s2 2s2 2p6 3s2 3p6 4s2 3d3

The neutral atom of vanadium is Argon. so, the electronic configuration of vanadium can also be written as,

     [Ar] 3d³ 4s²
