Document Summary

Periodic table: groups: columns on the periodic table. Elements in the same group will have similar properties. There are 18 groups on the periodic table: periods: rows on the periodic table. Elements in the same period will have different properties. Halogens, noble gases, representative elements, transition elements, inner transition. Elements: hydrogen group: h, alkali metals: group 1, except h, alkaline earth metals: group 2, halogens: group 17, noble gases: group 18, representative elements: groups 1-2, and 13-18, transition elements: groups 3-13.
