Astatine is a very unstable radionuclide so is not normally dealt with. A halide is a chemical compound of halogens bonded to more electro positive elements.
For more information, see Halomethane. Haloalkane or alkyl halides are the compounds which have the general formula â³RXâ³ where R is an alkyl or substituted alkyl group and X is a halogen (F, Cl, Br, I). Haloalkanes have been known for centuries.Chloroethane was produced synthetically in the 15th century.or more information, see Halomethane.
