(a) Nitrates of both group 1 and group 2 elements are soluble in water because hydration energy is more than the lattice energy.
Nitrates of both group 1 and group 2 elements are thermally unstable but they decompose differently except LiCO₃ e.g.

2NaNO₃ →2NaNO₂ + O₂

2KNO₃ →2KNO₂ + O₂

4LiNO₃ →2MgO + 4 N
