Assertion :- Metallic character increases on going down the group
Reason :- I.E. decreases on going down the group

Assertion :- Solubility of alkali metal hydroxide increases on moving down the group. Reason :- On moving down the group, hydration energy increases and lattice energy decreases.

The electron affinity increases in going down a group.

Assertion: Metallic character of first group metals of Mordern periodic table increase on moving down the group. Reason: On moving top to bottom in first group in Modern periodic table, value of ionisation enthalpy continuously decreases.
