Which of the following sequences of elements would all have four valence electrons?

A.) B, Si, As, Te

B.) C, Si, Ge, Sn

C.) O, S, Se, Te

D.) Ga, Ge, As, Se

Valency measures the number of electrons in the outer shell of an atom that can participate in a chemical reaction. In the group of answers provided, the elements that will have four valence electrons in their outer shells are group:

B.) C, Si, Ge, Sn

Elements in group fourteen have four elements in their outer shells.

Elements can enter into chemical bonds with other elements due to the sharing or donation of atoms in the valence shell.

Thus, a covalent or ionic bond can be formed through these relationships.

Therefore, the elements in group fourteen namely, carbon, Silicon, Germanium, and Tin (Stannum) all contain valence electrons.
