In the periodic table below, shade all the elements for which the neutral atom has a valence electron configuration of ns2np3 , where n stands for an integer.
Answer is: chemical elements in group 15 of the periodic table have neutral atom with a valence electron configuration of ns²np³. Nitrogen: [He] 2s² 2p³. Phosphorus: [Ne] 3s² 3p³. Arsenic: [Ar] 3d¹⁰ 4s² 4p³. Bismuth: [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p³. Moscovium: predicted [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p³. These elements have 5 valence electrons.
