Use the periodic table to identify the element indicated by each electron configuration by typing in the chemical symbol for the element. 1s^2 2s^2 2p^6:
1s^2 2s^2 2p^6 3s^2 3p^3:
1s^2 2s^2 2p^6 3s^2 3p^6 4s^1:
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8:
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^3:

Answer

The correct option is,

Explanation:

Electronic configuration : It is defined as the distribution or arrangement of electrons of an atom in atomic orbitals.

We are given that the atomic number of vanadium is, 23 that means the number of electrons present in vanadium is, 23.

The electronic configuration of vanadium will be,

Hence, the correct option is,

3
