Question

What are valance electrons

Answer 1

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

A valence electron is an electron of an atom, located in the outer most shell (called a valence shell) of the atom, which can be transferred to or shared with another atom.
