Hydride | chemical compound | Britannica
Hydride, any of a class of chemical compounds in which hydrogen is coined with another element. Three basic types of hydrides—saline (ionic), metallic, and covalent—may be distinguished on the basis of type of chemical bond involved. A fourth type of hydride, dimeric hydride, may also be identified on the basis of structure (see borane).
