We’re being asked to name the Mg(NO3)2. Recall that the cation is the positively charged ion in an ionic compound while the anion is the negatively charged ion.
The rules for naming polyatomic ionic compounds are as follows:
1. The metal keeps its name and is named and written first.
– For transition metals, we use Roman numerals to denote its charge.
2. Name the polyatomic ion as you would normally.
The cation in our formula is Mg which corresponds to Magnesium → main group (no roman numeral)
What is the systematic name of mg(no3)2?
