Alkaline Earth Metals
Group 2 elements in the periodic table are the alkaline earth metals.
Alkaline earth metals are in the 2nd column of the periodic table. They can lose up to 2 electrons without having to pull electrons out of an inner shell, and so alkaline earth metals almost always have a charge of +2
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
