• Determine the ion/ion charge for elements.
• Determine the number of cations and anions required to form an ionic compound.
• Write an ionic formula.
• Ionic Formula Activity
• Ionic Formula Activity – KEY

(All items compiled in 1 PDF document. Document cannot be edited.)
Additional Required Materials:
(These items are not included in the purchase.)
• Baggie for each “Ionic Formula Kit”
• Optional: Colored Printing, Cardstock, & Lamination
• Periodic Table per student
• Polyatomic Ion list per student
Print and cut-out tiles and directions for each group. Place tiles and instructions in baggie. Recommend preparing 12-15 kits.
• Prepare “Ionic Formula Kits”.
o Print “Ion Tiles” & “Ionic Formula Activity Kit Directions” (Optional: Print in color and laminate.)
o Cut-out “Ion Tiles” and place in container. Place “Ionic Formula Activity Kit Directions” in each kit.
o Label container – “Ionic Compound Formation Kit”.
• “Ionic Formula Activity” Instructions
o Place students in pairs or small groups.
o Give each student a copy of the “Ionic Formula Activity” WS.
o Give each group an “Ionic Formula Kit.”
o Read the instructions and demonstrate the example problem provided on the WS.
o Recommend: Set check points for the activity. For example, students must check with the teacher and SHOW ALL WORK with the “Ion Tiles” at problem #3, #6, and #10. At problem #3, the teacher checks all work for #1-3. At problem #6, the teacher checks all work for #4-6 and so on. Students are asked to correct or reconsider problems with mistakes. Place a stamp next to each problem or check point as it is completed correctly. (This way the teacher is grading while also providing formative feedback . This should set-up students to make a 100% on the assignment.)
• “CHALLENGE – Ionic Formula Activity” – For the challenge activity, students are not instructed which ions to use when forming ionic formulas.
o Students use the “Ionic Compound Formation Kit” to build as many neutral ionic compounds as possible. Students record their results on the “CHALLENGE – Ionic Formula Activity” WS.
Recommend: Require students to form a minimum number of compounds and then grant bonus points for extra compounds. For example, all students might be required to form 10 compounds. Each compound over 10 results in bonus points.
o Turn the assignment into a game!
After students have completed the regular “Ionic Formula Activity,” the CHALLENGE activity can be used as a game for a short review. If using the game format, it is not necessary to have students record their answers.
Game Option #1: Set a timer for 5 or 10 minutes. Have each group make as many compounds as possible. When the timer rings, the group with the most correct ionic compounds wins.
Game Option #2: Ask students to form 10 different compounds. The first group to correctly form 10 ionic compounds with the “Ion Tiles” wins!
• Assign the “Forming Ionic Formulas WS” for HW or further class practice.
