Twо mоlecules оf wаter аre diаgrammed above. Within a molecule of water, hydrogen atoms are joined to oxygen by a(n) [a] bond. This bond results in [b] charge on the oxygen atom and [c] charge on the hydrogen atom. As a result of this bond forming between hydrogen and oxygen, a(n) [d] bond can form between two separate water molecules.
