The Difference Between an Element Group and Period
Vertical columns on the periodic table represent families of elements with similar chemical properties called . groups. What are known as the main group or representative elements are designated by the numbers 1A through 8A (Group A elements). The elements known as . transition metals (Group B elements) span the distance between groups 2A and 3A.
