Interpretation:
The formulas for the compounds formed from the given elements that lie on the left and each polyatomic ion that lies on the right are to be written.
Concept introduction:
Metals lie at the left side of the periodic table.
The compounds consisting of positive ions (formed by metals) and negative ions (formed by nonmetals) are called ionic compounds.
Polyatomic ions are composed of a group of atoms having an overall charge.
The formula of ionic compounds containing polyatomic ions can be written by using the formula and charge of the polyatomic ions.
The steps for writing the formula of the ionic compound containing a polyatomic ion are listed below:
1. Write the symbol of the metal followed by the symbol for the polyatomic ion and their charges. The charge carried by the metal can be deduced from the group numbers in the periodic table.
2. The magnitude of the charge present on each ion is used as subscript for the other ion.
3. If possible, reduce the subscripts to simpler whole numbers.
4. Check that the sum of the charges of the cations cancels the sum of the charges of the anions.
