Nonmetal interhalogens

The interhalogens have properties intermediate between those of the constituent halogens. Nonmetals form covalent halides metals tend to form ionic halides. The oxoacids of chlorine are all oxidizing agents both acidity and oxidizing strength of oxoacids increase as the oxidation number of the halogen increases. 

Cation formation is not restricted, as normally observed, to association with metallic species. It can also occm among nonmetals and even the most typical ones such as halogens or interhalogens, which are usually more noted for halide and polyhalide anion formation. 

Again, like all compounds that form between two nonmetals, the interhalogen compounds contain covalent bonds. 

Halogens form ionic compounds with most metals, they form covalent compounds with many nonmetals, and they can bond with themselves to form interhalogen compounds. Here we look at some of these halogen compounds.
