Question

Answer (score: 0.5): 3. Atoms of which two elements in the ground state have the electron formula of the outer energy level ns^2np^2 1) C 2) Si 3) Mo 4) Ga 5) S

Answer 1

The correct answer is 1) C and 2) Si.The electron configuration

corresponds to the valence electron configuration of elements in Group 14 (or IV A) of the periodic table. In the ground state, the electron configuration of carbon (C) is

, and the electron configuration of silicon (Si) is

. Both carbon and silicon have the electron configuration

in their outer energy level.
