Solution
Beryllium hydroxide(Be(OH)2) is amphoteric in nature whereas the hydroxides of barium,strontium and calcium are basic in nature.
Beryllium hydroxide reacts with acids as well as bases. The amphoteric nature of beryllium is due to small size, high electronegativity and high ionization energy of beryllium.
