Number of electrons that Vanadium (Z = 23) has in p-orbitals is equal to:

Vanadium has atomic number $$Z = 23$$. Its electronic configuration is $$1s^2\, 2s^2\, 2p^6\, 3s^2\, 3p^6\, 3d^3\, 4s^2$$.

The electrons in p-orbitals come from the $$2p$$ and $$3p$$ subshells. The $$2p$$ subshell holds 6 electrons and the $$3p$$ subshell holds 6 electrons, giving a total of $$6 + 6 = 12$$ electrons in p-orbitals.

The answer is $$12$$.
