Periods & Groups In The Periodic Table

The video tutorial explains the periodic table's structure, highlighting the organization of elements into periods and groups. Periods are horizontal rows where elements share the same number of energy shells, while groups are vertical columns where elements have the same number of valence electrons. The tutorial uses examples like hydrogen and potassium to illustrate periods and group 7 elements like fluorine and chlorine to explain group properties. It emphasizes how these arrangements help predict element reactivity and chemical characteristics.
