Radii in picometers of common halogen atoms (gray/black) and the corresponding halide anions (blue)|right|thumb|120px In chemistry, a halide (rarely halogenide) is a binary chemical compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or theoretically tennesside compound. The alkali metals combine directly with halogens under appropriate conditions forming halides of the general formula, MX (X = F, Cl, Br or I). Many salts are ha

卤化物指含有呈负价卤素的化合物，通常为二元化合物。卤离子则指相应-1价的卤素离子。根据具体卤素的不同，卤化物可分为： * 氟化物 — F− * 氯化物 — Cl− * 溴化物 — Br− * 碘化物 — I− * 砹化物 — At− 拟卤素生成的-1价化合物称为拟卤化物，主要有叠氮化物N3−、氰化物CN−、硫氰酸盐SCN−和氰酸盐OCN−等。 互卤化物则指只由卤素构成的二元化合物，如ICl、ClF3、IF5等。 有机化学中，有时也用卤化物来指卤代烃，简写为R-X。根据具体卤素的不同亦可分类为氟代烃、氯代烃、溴代烃和碘代烃。二卤代烷常用于环的构建，参见卡宾。
