Interhalogens Defined
Captions available
The idea
An interhalogen is a compound of two different halogens, typically one atom of a heavier halogen bonded to an odd number of lighter atoms.
In practice
Iodine pentafluoride, IF5, pairs one heavier iodine atom with five lighter fluorine atoms.
Where people slip
Interhalogens differ from halide salts formed with metals — both halogen atoms here are nonmetals bonded covalently to each other.
