(i) Beryllium halides are covalent whereas magnesium halides are ionic. Why?
(ii) What happens when
1. Sodium metal is dropped in water?
2. Sodium metal is heated in free supply of air?
3. Sodium peroxide dissolves in water?

Text Solution

Verified by Experts

(i) Beryllium ion `(Be^(2+))` is smaller in size and it is involved in equal sharing of electrons with halogens to form covalent bond, whereas magnesium ion `(Mg^(2+))` is bigger and it is involved in transfer of electrons to form ionic bond.
(ii) 1.` 2Na+2H_(2)O+2NaOH+H_(2)`
2. `2Na+O_(2)toNa_(2)O_(2)`
3. `Na_(2)O_(2)+2H_(2)Oto2NaOH+H_(2)O_(2)`
