Step 1

1 Reactivity of the elements increases.

Answer

This statement is correct. As you move down Group 2, the reactivity of the elements increases. This is due to the fact that the outer electron is further from the nucleus, which makes it easier to lose.

Step 2

2 First ionisation energy of the elements decreases.

Answer

This statement is also correct. The first ionisation energy decreases down the group because the outer electrons are at higher energy levels and experience increased shielding from the nucleus, making them easier to remove.

Step 3

3 The hydroxides become more soluble in water.

Answer

This statement is correct as well. The solubility of group 2 hydroxides in water increases down the group, making the hydroxides more soluble with strontium and barium hydroxides being highly soluble.
