The elements astatine ( At) and radon ( Rn) are both in period 6. Summary The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. Many terms have been used in the literature to describe sets of elements that behave similarly. The group names alkali metal, alkaline earth metal, triel, tetrel, pnictogen, chalcogen, halogen, and noble gas are acknowledged by IUPAC; the other groups can be referred to by their number, or by their first element (e.g., group 6 is the chromium group).
