Answer is: chemical elements in group 15 of the periodic table have neutral atom with a valence electron configuration of ns ² np ³.

Nitrogen: [He] 2s² 2p³.

Phosphorus: [Ne] 3s² 3p³.

Arsenic: [Ar] 3d ¹⁰ 4s² 4p³.

Bismuth: [Xe] 4f ¹⁴ 5d¹⁰ 6s² 6p³.

Moscovium: predicted [Rn] 5f¹⁴ 6d ¹⁰ 7s ² 7p³.

These elements have 5 valence electrons.
