About this model

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.
