+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)

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

The ability to attract electrons. Fluorine is the king here. 2. The s-Block (Groups 1 & 2) MAIN GROUP CHEMISTRY, (Tutorial Chemistry Texts)
