The Alkaline Earth Metals (Group 2)
As with the alkali metals, the atomic and ionic radii of the alkaline earth metals increase smoothly from Be to Ba, and the ionization energies decrease. As we would expect, the first ionization energy of an alkaline earth metal, with an ns 2 valence electron configuration, is always significantly greater than that of the alkali metal immediately preceding it.
