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.).
from wikipedia the free encyclopedia the periodic table of the chemical elements is a tabular display of the known chemical elements the elements are arranged by electron structure so that many chemical properties vary regularly across the tableeach element is listed by its atomic number and chemical symbol group is a vertical column in the periodic table of the elements there are 18 groups in the standard periodic table elements in a group have similar configurations of their valence shell electrons which gives them similar properties
