Question

1. The valence electrons of representative elements are

a) located in the outermost energy level.
b) located closest to the nucleus.
c) anywhere in the atom
d) located in the outermost occupied shell.

Answer 1

a) located in the outermost energy level.

Step-by-step explanation:

A valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
