6. Atoms can gain or lose electrons to become chemically stable. An atom is
stable when it gains valence electrons to reach a total of 8 valence
electrons, or loses valence electrons to achieve an empty outer shell (0
valence electrons). Based on this information, identify two elements that
could form a chemical bond by one atom losing electrons and the other
atom gaining these electrons.
