State the electronic configuration of group-$15$ elements.

The valence shell electronic configuration of group-$15$ elements is $ns^{2}np^{3}$. The detailed electronic configurations are as follows:

Element	Electronic configuration
${ }_{7} N$	$[He] 2s^{2} 2p^{3}$
${ }_{15} P$	$[Ne] 3s^{2} 3p^{3}$
${ }_{33} As$	$[Ar] 3d^{10} 4s^{2} 4p^{3}$
${ }_{51} Sb$	$[Kr] 4d^{10} 5s^{2} 5p^{3}$
${ }_{83} Bi$	$[Xe] 4f^{14} 5d^{10} 6s^{2} 6p^{3}$
${ }_{115} Mc$	$[Rn] 5f^{14} 6d^{10} 7s^{2} 7p^{3}$

All elements of group-$15$ have $5$ electrons in their valence shell. Hence,the general electronic configuration is $ns^{2}np^{3}$.
