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.
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.
Magnesium oxide, or MgO, is an ionic compound: the result of a metal reacting with a non-metal.
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.
No, lithium oxide is an ionic compound. Ionic compounds are formed by the transfer of electrons between a metal and a nonmetal, whereas molecular compounds are formed by sharing electrons between nonmetal atoms. In lithium oxide, lithium is a metal, and oxygen is a nonmetal, resulting in an ionic bond.
Lithium oxide does not exist as molecules, as it is an ionic compound.
