Following instructions on the element card
Complete the element card and determine the charge of the ion
Only ionic bonds (+ bonds -) unless instructed
Only two elements can bond (e.g., hydrogen and chlorine only) unless instructed
You need to locate the correct ratio of ions to bond (e.g., K 2O required two potassium
and one oxygen). You determine the ratio by comparing ionic charges. In this case,
oxygen needs to gain two electrons while potassium has one electron to give.
HINT: Use coloured paper to represent different elements.
Instructions
1. Each student is assigned one element card
2. Rules of the game are provided
3. Students complete the chart on their element card to determine the Ionic Charge
4. Students search the room for students with ions that could bond to their ion according to
the rules on each element card (e.g., potassium looks to bond with oxygen). Student
need to determine the correct ratio of ions to create the compound. As noted, three
students (two potassium and one oxygen) must come together to bond and form
potassium oxide
5. Once “bonded,” students draw a diagram of their compound (i.e., Bohr-Rutherford or
Lewis Dot) and explain the bonding.
6. Debrief with students explaining Ionic Bonds and demonstrate a correct diagram
7. Shuffle and redistribute cards to repeat process to ensure learning
