No. Iron III oxide is an ionic compound. This is due to the large difference in electronegativity between oxygen and iron. If the electronegativity difference is greater than 2.0 a compound is generally ionic. The difference between iron and oxygen is 2.61.
Iron oxide is an ionic compound.
Nitrogen oxide is a molecular compound, not an ionic compound. It is composed of nitrogen and oxygen atoms bonded together covalently.
Cr2O3 is an ionic compound. It consists of chromium ions (Cr3+) and oxide ions (O2-) held together by ionic bonds.
Fe2O3
Magnesium oxide is an ionic compound with the formula MgO.
Magnesium oxide, or MgO, is an ionic compound: the result of a metal reacting with a non-metal.
No, Sc2O3 is an ionic compound, not a molecular compound. It is composed of scandium ions (Sc3+) and oxide ions (O2-), which are held together by ionic bonds.
Sulfate oxide is an ionic compound. It is composed of sulfate ions (SO4^2-) and oxide ions (O^2-), which are held together by ionic bonds.
The electronegativity variance here is not great enough to make this an ionic compound, so nitrous oxide is covalent and molecular.
Zinc oxide is an ionic compound because it is made up of zinc cations (Zn2+) and oxide anions (O2-), which are held together by ionic bonds.
Nitrous oxide is a molecular compound. It consists of covalent bonds between nitrogen and oxygen atoms, with the formula N2O.
PbO2 is an ionic compound composed of lead (Pb) and oxide ions (O2-) bound together by ionic bonds.
