+2 oxidation state. Harder and less reactive than Group 1, but still form basic oxides. Magnesium and Calcium are biologically essential. 3. The p-Block (Groups 13–18)

Decreases across a period (increasing nuclear charge pulls electrons closer) and increases down a group. MAIN GROUP CHEMISTRY, (Tutorial Chemistry Texts)

This is where chemistry gets diverse, moving from metals to metalloids to non-metals. +2 oxidation state
