Understand that the empirical formula represents the simplest whole-number ratio of atoms of each element in a compound.
Identify the elements involved: magnesium (Mg) and oxygen (O).
Recognize that magnesium typically forms a +2 charge (Mg^{2+}) and oxygen typically forms a -2 charge (O^{2-}) when forming ionic compounds.
Balance the charges to find the simplest ratio: since Mg^{2+} and O^{2-} have equal and opposite charges, they combine in a 1:1 ratio.
Write the empirical formula using the simplest ratio of atoms, which is MgO.
