Explanation:

The #"representative elements"# are a bit of an old-fashioned term, and refers to the Group 1 and Group 2 metals, i.e. the alkali metals, and the alkaline earths, and the non-transition metal elements in Groups 13 to 18.....

All of these elements have typically (but not exclusively) the one oxidation state (there are of course subvalent compounds), and fairly predictable chemistry in terms of symmetry and reactivity.
