No, iron and chlorine do not form an ionic compound. Ionic compounds are formed when a metal atom loses electrons to a non-metal atom. Iron is a metal, but chlorine is a non-metal. However, chlorine has a higher electronegativity than iron, which means that it has a greater attraction for electrons. This causes the chlorine atoms to gain electrons from the iron atoms, forming covalent bonds rather than ionic bonds. The compound formed between iron and chlorine is iron(III) chloride (FeCl3), which is a covalent compound.
