The ground state electronic configurations of the elements, \( U, V, W, X \), and \( Y \) (these symbols do not have any chemical significance) are as follows :
\( \mathrm{P} \)
\[
\begin{array}{ll}
U & 1 s^{2} 2 s^{2} 2 p^{3} \\
V & 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{1} \\
W & 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{2} \\
X & 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{5} 4 s^{2} \\
Y & 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{10} 4 s^{2} 4 p^{6}
\end{array}
