The first ionisation energies of alkaline earth metal are higher than those of the alkali metals. This is because:

The first ionization energies of alkaline earth metal are higher than those of the alkali metals. This is because:

The first ionization energies of alkaline earth metals are higher than those of the alkali metals. This is because

Why first ionization energy of alkaline earth metals is higher than that of alkali metals?

The first ionisation enthalpies of the alkline earth metals are higher than that of alkali metals but second ionisation ethalpies are smaller, why?

The first ionisation enthalpies of the alkline earth metals are higher than that of alkali metals but second ionisation ethalpies are smaller, why?

The densities of alkaline earth metals are much smaller than those of alkali metals.
