s
  • Elements in the same Group in the Periodic Table will have similar chemical properties as they have the same number of outer Electrons so will react and bond similarly
  • For example, both Lithium and Sodium are in Group 1 and can react with Elements in Group 7 to form an Ionic Compound (charges of Group 1 Elements are +1, charges of Group 7 Elements are -1)
