1.	An element of group 2 forms covalent oxide which is amphoteric in nature and dissolves in water to give an amphoteric hydroxide . Identify the element and write chemical reactions of the hydroxide of the element with an alkali and an acid .
Answer» Solution :Because of small size and comparatively high electronegativity of Be , BeO is covalent . It is INSOLUBLE in water . It is amphoteric in nature and DISSOLVES in acids as well as alkalies . `BeO + 2 HCL to BeCl_(2) + H_(2)O` `BeO + 2NaOH to underset("Sod. beryllate")(Na_(2)BeO_(2) +) H_(2)O`
