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 the charges of the ions involved. Zinc typically forms a +2 charge (Zn^{2+}), and oxygen typically forms a -2 charge as the oxide ion (O^{2-}).
Combine the ions in a ratio that results in a neutral compound. Since Zn^{2+} and O^{2-} have charges that balance one-to-one, the formula ZnO is neutral.
Name the compound using IUPAC conventions for ionic compounds: name the metal first (zinc), followed by the nonmetal with its ending changed to '-ide' (oxide), resulting in 'zinc oxide'.
