Correct answer: 12

Write the electronic configuration of Vanadium

Vanadium has atomic number $Z = 23$ , so it has $23$ electrons.

Its ground-state electronic configuration is:

1s^2\,2s^2\,2p^6\,3s^2\,3p^6\,3d^3\,4s^2

Identify electrons present in all p-orbitals

The occupied p-subshells are:

$2p^6$
$3p^6$

There is no electron in $4p$ for vanadium.

Count total p-electrons

2p^6 + 3p^6 = 6 + 6 = 12

Final answer

Therefore, the number of electrons in p-orbitals in vanadium is:

\boxed{12}

Comparison with stored correct answer

Stored correct answer = $12$

My derived answer also = $12$ , so they agree.
