Question

Why are valence electrons important?

Answer 1

Explanation:

In chemistry and physics, a valence electron is an outer shell electron that is 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.

Answer 2

Answer:

$\huge\fbox\red{✰answer}$

The electrons that occupy the outer most shell of an atom are called valence electrons. They are important because they determine how an atom will react. By writing an electron configuration, You'll be able to see how many electrons occupy the highest energy level.
