Question:

How many pairs of bonding and nonbonding valence electrons are in this molecule?

(a) 3 pairs of bonding electrons, 3 pairs of nonbonding electrons

(b) 4 pairs of bonding valence electrons, 2 pairs of nonbonding valence electrons

(c) 4 pairs of bonding valence electrons, 4 pairs of nonbonding valence electrons

(d) 2 pairs of bonding valence electrons, 4 pairs of nonbonding valence electrons

Valence Electrons

Valence electrons are the electrons in the outermost shell of a given atom. These are the electrons that are capable of engaging in any bonding interaction with other atoms through covalent or ionic interactions.

Answer and Explanation: 1

Given that no molecule is shown, I will outline what it means to have nonbonding and bonding electrons. Bonding electrons are those electrons in a Lewis structure which directly form covalent linkages between two atoms, such as a C-C linkage. Nonbonding electrons, found in elements such as nitrogen in the -NH2 form, are lone pair electrons that are not currently engaged with other atoms in a bonding interaction, but are capable of doing so.
