These characteristics increase with a larger nuclear charge and smaller radius, with no increase in shielding. The most active non-metal would be the one farthest up and to the right -- not including the noble gases (non-reactive.)

Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.

Elements that exhibit similar chemistry appear in vertical columns called groups (numbered 1–18 from left to right); the seven horizontal rows are called periods. The elements can be broadly divided into metals, nonmetals, and semimetals. Semimetals exhibit properties intermediate between those of metals and nonmetals.

If, for example, a solution of Cl 2 in H 2 O is combined with a solution of NaI, the dark color of I 2 can be observed, showing that the Cl 2 has oxidized the I – :

The sodium or potassium ions are spectator ions and therefore irrelevant to the reaction, which proceeds as follows:
