Metals which can produce amphoteric oxides
In chemistry, an amphoteric compound (from Greek amphi- 'both') is a molecule or ion that can react both as an acid and as a base. What exactly this can mean depends on which definitions of acids and bases are being used. One type of amphoteric species are amphiprotic molecules, which can either donate or accept a proton (H ).
