The halogen refer to the actual elements in the halogen group like fluorine and chlorine and bromine..idodine ect ect the halide could be used to describe a compound with a halogen in it, For example combine the alkali metals with a halogen and you get an alkylhalide (sodium bromide), an organic molecule with a hologen in it would be an organohalide ( chloromethane)
