Answer: Option (1) is the correct answer.
Explanation:
A bond formed by transfer of electrons from one atom to another is known as an ionic bond.
Generally, an ionic bond is formed between a metal and a non-metal.
When a bond is formed by sharing of electrons then it is known as a coavlent bond.
A covalent bond is formed only within non-metals.
Chemical formula of iron(III) oxide is [tex]Fe_{2}O_{3}[/tex]. Here, iron is the metal and oxygen atom is the non-metal.
Hence, bond formed within both the elements will be ionic in nature due to transfer of electrons from iron to oxygen atom.
Thus, we can conclude that the bonds in iron(III) oxide are more ionic.
