chemical bond CORRECT ANSWER the force that holds two atoms together Atoms gain stability when CORRECT ANSWER they share electrons and form covalent bonds. The stability of an atom, ion or compound is related to its energy: CORRECT ANSWER lower energy states are more stable Metals and nonmetals gain stability by CORRECT ANSWER transferring electrons (gaining or losing) to form ions that have stable noble-gas electron configurations. Another way atoms can gain stability is CORRECT ANS...
