Answer:
In group 2, Be is the only element that gives covalent oxide BeO, which is amphoteric in nature.
The rest elements of this group give ionic oxides which are basic in nature. Be0 dissolves in water and gives sparingly soluble hydroxide which reacts with acid and base to give salt
BeO+H 2 O→Be(OH)2
Be(OH) 2 +2OH − →[Be(OH) 4 ] 2−
Beryllate ion
Be(OH)² +2HCl+²H ²O→[Be(OH)4 ]Cl2
