Is ibr ionic or covalent?
IBr contains covalent bonds. Covalent bonds are present in compounds that are formed from the combination of nonmetals. IBr contains covalent bonds because both iodine and bromine are nonmetallic elements. BaO and LiBr contain ionic bonds because these compounds are formed from the combination of metals and nonmetals.
