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