Why isn't iron bromide magnetic?

Iron bromide isn't magnetic because it is composed of iron ions (Fe²⁺ or Fe³⁺) and bromide ions (Br⁻), which form ionic bonds. In this compound, the magnetic properties of iron are neutralized by pairing of electron spins in the ionic lattice, leading to no net magnetic moment. Additionally, the presence of bromide, a non-magnetic ion, contributes to the overall non-magnetic character of the compound. As a result, iron bromide does not exhibit the ferromagnetic behavior seen in elemental iron.
