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

As it happens, iron (III) sulfate is both ionic and covalent! iron cations are ionically bonded to polyatomic sulfate anions, and the sulfur and oxygen atoms of the polyatomic anions are covalently bonded within these anions.

Its ionic mainly because Ionic bonding occurs between a cation and an anion (often a metal and a nonmetal).

Quite simply, it is ionic, it contains a metal element and at least one non-metal element, bonded into a compound.
