Verified step by step guidance1
Identify the elements present in the compound. Here, the compound consists of zinc (Zn) and oxygen (O).
Determine the type of compound. Since zinc is a metal and oxygen is a nonmetal, this is an ionic compound.
Recall that in ionic compounds, the metal (cation) is named first, followed by the nonmetal (anion) with its ending changed to '-ide'.
Check the common oxidation states of zinc. Zinc typically forms a +2 charge (Zn²⁺) and does not require a Roman numeral in its name because it has only one common oxidation state.
Name the compound by combining the metal name 'zinc' with the nonmetal root 'oxide' (from oxygen), resulting in the IUPAC name 'zinc oxide'.
