Why the alkaline earth metals are strong reducing agents?

Beryllium has a more negative value(electron gain enthalpy) compared to other alkaline earth metals.

Beryllium has the highest sublimation enthalpy among the Group-$2$ elements.

Identify the Group-$2$ element which has the highest sublimation enthalpy.

Write the variation of enthalpy of sublimation in the Group-$2$ elements.

Which alkaline earth metal is present in chlorophyll?

Write the uses of alkaline earth metals.

The element whose salts cannot be detected by flame test is.

$\mathrm{Ca}$ bums with ${\mathrm{N}}_2$ to produce a white powder which dissolves in water to give a gas $\text{'}\mathrm{X}\text{'}$' and a solution with $\mathrm{pH}>7.$ The solution on exposure to air produces a thin solid layer of $\text{'}\mathrm{Y}\text{'}$ on the surface. The compounds $\text{'}\mathrm{X}\text{'}$ and $\text{'}\mathrm{Y}\text{'}$ are ______
