The inner shells of an atomâs electrons are full and stable. For the most part, they contribute little to the way the atom reacts. The largest factor in how an atom reacts is the makeup of its outer shell electrons. The periodic table naturally groups together elements with similar outer shells (Transition metals, halogens, etc.).
Definitions of groups, periods, alkali metals, alkaline earth metals, halogens, and noble gases. How metals, non-metals, and metalloids can be identified by the position on the periodic table.
