1.23: Understand Why Elements in the Same Group of the Periodic Table have Similar Chemical Properties

GROUP: Vertical columns that show how many outer Electrons an Atom has

CHEMICAL PROPERTIES OF ELEMENTS IN THE SAME GROUP:

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)
