The '''halides''' are [[compounds]] in which a [[halogen]] [[element]] ([[chlorine]], [[fluorine]], [[iodine]], or [[bromine]]) is the sole [[anion]], as in [[halite]] ([[sodium chloride]]), NaCl. These [[minerals]] are relatively soft, weak, and [[brittle]], and many of them will [[dissolve]] readily in [[water]]. Those that are not [[soluble]] in water generally [[crystallize]] in the [[isometric]] [[crystal system]] and develop as [[cubes]].
