Halide
A
halide is a binary compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative than the halogen, to make a fluoride, chloride, bromide, iodide, or astatide compound. Many salts are halides; the
hal- syllable in
halide and
halite reflects this correlation. All Group 1 metals form halides that are white solids at room temperature. A
halide ion is a halogen atom bearing a negative charge. The halide anions are fluoride, chloride, bromide, iodide and astatide. Such ions are present in all ionic halide salts. Halide minerals contain halides. See chloride, bromide, fluoride, and iodide...
