Question

Is ${\mathrm{Fe}}_2{\mathrm{O}}_3$ it a covalent or ionic bond?

Answer 1

Explanation:

Iron oxide, also known as ferric oxide, is composed of three oxygen atoms and two iron atoms.

1. Its chemical formula is${\mathrm{Fe}}_2{\mathrm{O}}_3$.
2. Iron oxide has $+3$ and $+2$ oxidation states.
3. The bond between iron and oxygen is formed due to the difference in electronegativity between the two atoms. Because iron is metal and oxygen is non-metal, the bond between the two is ionic.

Hence, ${\mathrm{Fe}}_2{\mathrm{O}}_3$ is an ionic bond, not a covalent.
