A general term for all metals in group IIA of the periodic table ([[beryllium|beryllium]], [[magnesium|magnesium]], [[calcium|calcium]], [[barium|barium]], [[strontium|strontium]], and [[radium|radium]]). Alkaline earth metals are usually white, malleable, extrudable and machinable. The divalent alkaline earth metal anions form stable oxides (alkaline earths) and carbonates. Additionally, they are less reactive than alkali metals (i.e., [[sodium|sodium]] and [[potassium|potassium]]) and they form hydroxides that are less soluble and less basic than the alkali metal hydroxides. | A general term for all metals in group IIA of the periodic table ([[beryllium|beryllium]], [[magnesium|magnesium]], [[calcium|calcium]], [[barium|barium]], [[strontium|strontium]], and [[radium|radium]]).

Description
A general term for all metals in group IIA of the periodic table (Beryllium, Magnesium, Calcium, Barium, Strontium, and Radium). Alkaline earth metals are usually white, malleable, extrudable and machinable. The divalent alkaline earth metal anions form stable oxides (alkaline earths) and carbonates. Additionally, they are less reactive than alkali metals (i.e., Sodium and Potassium) and they form hydroxides that are less soluble and less basic than the alkali metal hydroxides.
