The term "ion" is fairly general and it breaks up into cations and anions.

Cation has positive charge because it lost one or more electrons.

Anion has negative charge because it gained one or more electrons.

the answer is true.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
