# Number of electrons

Question:

Number of electrons that Vanadium $(Z=23)$ has in p-orbitals is equal to__________.

Solution:

${ }_{23} \mathrm{~V}: 1 \mathrm{~s}^{2} 2 \mathrm{~s}^{2} 2 \mathrm{p}^{6} 3 \mathrm{~s}^{2} 3 \mathrm{p}^{6} 3 \mathrm{~d}^{3} 4 \mathrm{~s}^{2}$

Number of electrons in $\mathrm{p}$-orbitals is equal to $12.00$
