A group is a vertical column on the periodic table. A period is a horizontal row on the periodic table. Elements in the same group tend to have similar physical and chemical properties. The elements in a period have no discernible similarities; the atomic numbers of elements in a period increase by one as we move from left to right on the periodic table.
