SHORT ANSWER
28. Atoms form chemical bonds to establish a more-stable arrangement. As independent particles, they are at high potential energy. By bonding, they decrease their potential energy, thus becoming more stable.
29. Atoms in a molecular compound share electrons to achieve stability. Atoms in an ionic compound gain or lose electrons to form ions.
30. An ion is a positively or negatively charged atom; an ionic bond occurs when oppositely charged ions attract each other and an equal exchange of electrons takes place.
