Is CaO an alkali or a base? | Socratic
Metal oxides are basic, non-metal oxides are acidic. Now, we need to check if it''s soluble or not, as if it is soluble, it''s considered an alkali, but if it''s insoluble, it is a base. The solubility rule states that for oxides and hydroxides, most are insoluble, with the exceptions of sodium, potassium, and more.

The Alkaline Earth Metals (Group 2) - 2012
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.
