b. There are two very important exceptions to this which you have probably
already seen. These are water (H2O) and ammonia (NH3). Both of these have common
names, which are firmly established in the nomenclature, property of these two
compounds which makes them different from almost all others is the ability to readily
accept a proton (coordinate covalent bond with a hydrogen cation) to form cations.
Thus water becomes hydronium ion (H3O+1); ammonia becomes ammonium ion
(NH4+1) very easily in the right conditions.
