The Alkaline Earth Metals (Group 2) - GitHub Pages
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.
Alkaline Earth Metals - Home
Calcium is an alkaline earth metal. It''s melting point is 1542.2 F and boiling point is 2703.2 F. It''s a silver color. The density of calcium is 1.55 g/cm3. Calcium is used in bone structures and the sturcture of other types of shells. It can be obtained from chalk
