It is ionic because chromium is a metal.
Cr2O3 is an ionic compound. It is composed of chromium (Cr) and oxygen (O) ions that are held together by ionic bonds.
Glucose is a molecular compound, not ionic. It consists of covalent bonds between its carbon, hydrogen, and oxygen atoms.
HCIO4 is an ionic compound.
NO is a molecular compound, not an ionic compound. It is made up of individual atoms of nitrogen and oxygen that are covalently bonded together.
The molecular formula of sulfur dioxide (SO2) is molecular, not ionic. This compound is made up of covalent bonds between sulfur and oxygen atoms, where they share electrons to form the molecule.
Cr2O3 is an ionic compound. It is composed of chromium (Cr) and oxygen (O) ions that are held together by ionic bonds.
It is ionic compound as the difference in the electronegativity between chromium and oxygen is more than 1.7

You misunderstand. !!!! Magnesium is an ELEMENT. As an element it exists as atoms in a metallic lattice. When combined with another element e.g. oxygen as magnesium oxide, (MgO), then it is an ionically bonded molecular compound. Mg^(2+) + O^(2-) = MgO(s)
A molecular covalent compound
