In group 2 only Be gives covalent oxide, which is amphoteric in nature. The rest elements in the group give ionic oxide, which is basic in nature. BeO on dissolving in water gives sparingly soluble hydroxide which reacts with acid and base to give salt.

BeO+H_{2}O \rightarrow Be(OH)_{2}

Be(OH)_{2}+2OH^{-} \rightarrow \left [BeOH_{4} \right ]^{2-}

Be(OH)_{2}+2HCl+2H_{2}O \rightarrow \left [Be(OH)_{4} \right ] Cl_{2}
