Question

Write the symbols, with charges, for ions formed by calcium, magnesium, strontium, potassium, and sodium, as well as the ions chloride and nitride. Write formulas and names for the compounds you can make by pairing each of the cations with each of the anions.

I will show you what I have so far. I just didn't know how to do cations and anions. I tried anions but don't know if they are right and maybe it needs to be a formula. Thanks

Charge    Anion Chloride Nitride Cation

Calcium    Ca^2+ Cl^-1     CaCl2 Ca3N2

Magnesium Mg^2+ P^-3     MgCl2 Mg3N2

Strontium Sr^2+         SrCl2 Sr3N2

Potassium K^+ S^-2 KCl KNO2

Sodium Na^+ Cl^-    NaCl Na3N2
