Answer: The main difference between electrons and valence electrons is their location within the atom.
Explanation: Electrons are negatively charged particles that orbit around the nucleus of an atom. They are responsible for the chemical behavior of atoms. Valence electrons, on the other hand, are the electrons in the outermost energy level or shell of an atom. They are involved in the formation of chemical bonds between atoms. Electrons can be found in different energy levels, while valence electrons are specifically found in the outermost energy level.
