Question

What are valence electrons and why are they so important in chemistry?

Answer 1

Valence electrons is an electron that can participate in the formation of a chemical bond.Also, valence electrons have the ability to absord or release energy in the form of a photon. Valence electrons are in the energy level that is farthest aways from the nucleus. The valence electrons are the ones, that in a chemical reaction, are gained, lost or shared.

Answer 2

valance electrons that reside in the outermost shell of an atom in the highest energy level. They are important to atoms because the fewer valence electrons that the atom holds, it becomes less stable.

I take honors chemistry I hope this helps.
