a)
Interpretation: The formula of the ionic compound to be predicted.
Concept Introduction:
Polyatomic Ions: An ion that is composed of more than one atom.
Ionic compound: A compound that contains ionic bonds.
Formula of Ionic compounds:
Once the number and kinds of ions in a compound are known, the formula is written using the following rules;
- List the cation first then the anion.
- Do not write the charge of the ions.
- Use parentheses around a polyatomic ion formula if it has a subscript
