Chemical Formula Writing Worksheet
Write chemical formulas for the compounds in each box. The names are found
by finding the intersection between the cations and anions. Example: The first
box is the intersection between the “zinc” cation and the “chloride” anion, so you
should write “Zn Cl
”, as shown.
