Manipulatives students can use to make ionic compounds and write their chemical formulas.
Print positive and negative ions in different colors.
The models pictured were printed at 70% to reduce the printing time.
I added blank pieces so you can make additional ions by adding the symbol and charge, or just print the blanks and write them on with a marker.
I made a new Iodide so the I won't be confused with a lowercase l in Al and Cl.
