Ionic. Iron can be present as Fe2+ or Fe3+. Oxygen is present as the oxide ion O2-

The bond is ionic.
ionic
It is an ionic compound.
Metallic bonding is exhibited in an iron nail.
Elemntal iron is a metal with metallic bonding. In its compounds the bonding can be ionic or covalent.
Electronegativity Fe = 1.83; O = 3.44 3.44 - 1.83 = 1.61 Since the electronegativity difference is 1.61 the bond is polar covalent 0 - 0.4 = Pure Covalent Bond 0.41 - 1.7 = Polar Covalent Bond 1.7 + = Ionic Bond
Ionic because it is made of a metal and a non-metal bonded.
First of all Fe is Iron, and a sample of Iron would just be pure Iron thus there wouldn't be any "bonds" Second of all Fe is a metal thus cannot have a covalent bond. If it bonds, it is usually an ionic bond with non-metal i.e. Oxygen to make rust
