The outermost electrons, also known as valence electrons, are the ones involved in chemical bonding and determining the chemical properties of an atom. Electrons in the innermost shell are tightly bound to the nucleus and not involved in chemical reactions. Electrons in the middle shells have some involvement in chemical bonding, but not to the same extent as the valence electrons in the outermost shell. Therefore, choice C is the correct answer.
