What types of bond is Fe?

Iron (Fe) primarily forms metallic bonds, as it is a metal. In these bonds, electrons are shared collectively among a lattice of iron atoms, allowing for properties like conductivity and malleability. Additionally, iron can form ionic bonds when it reacts with nonmetals, such as in iron(III) chloride (FeCl₃), where it loses electrons to form cations. It can also participate in covalent bonds in certain compounds, although this is less common.
