c. a bond between a hydrogen atom already covalently bound to one atom and made partially positive by unequal electron sharing with another atom.
d. weaker than van der Waals forces.
e. exemplified by the two hydrogens covalently bound to oxygen in the water molecule.

In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg.
