They must combine with atoms of other elements to become stable.When an atom of one element enters into chemical combination with another element, both atoms usually attain a stable outer shell consisting of eight electrons.If the game is successful, students will discover logical pairings of whole families on the periodic table.
The article presents the Atomic Dating Game design to help students visualize atoms combining and to increase student understanding of how, and why combination occurs.
