Verified step by step guidance1
Identify the elements involved in the compound: Mg (magnesium) and O (oxygen).
Recognize that Mg is a metal and O is a nonmetal, so the compound is ionic.
Determine the charges of the ions: Mg typically forms a +2 ion (Mg^{2+}), and O typically forms a -2 ion (O^{2-}).
Since the charges balance 1:1, the formula MgO is neutral without needing any subscripts.
Name the compound by stating the metal name first (magnesium) followed by the nonmetal root with the suffix '-ide' (oxide), resulting in 'magnesium oxide'.
