We’re being asked to name CuNO4.
Recall that ionic compounds with polyatomics feature a cation that can be a positive metal or polyatomic ion and an anion that can be a negative nonmetal or polyatomic ion.
Rules for naming ionic compounds with polyatomics:
1) The metal keeps its name and is named and written first. If the metal is a transition metal we must use a Roman Numeral to describe its positive charge
2) Name the polyatomic as you would normally
Name each ionic compound containing a polyatomic ion.
