Interpretation:
The chemical formulas for the compound formed from ions
Concept Introduction:
Chemical formulas and names for ionic compounds containing polyatomic ions:
Ionic compounds containing positive and negative charges present must add to zero.
If more than one polyatomic ion is present in a compound, the chemical formula can be written as a polyatomic ion is enclosed in parentheses and a subscript, placed outside of the parentheses. Example-
Sometimes same element is present at two different locations. For example,
