4.- HYDRIDES 4.1.- Metallic hydrides 4.1.a. MULTIPLICATIVE PREFIXES NOMENCLATURE Hydrides are combinations of a metal with hydrogen. Hydrogen has oxidation number -1; the metal has a positive oxidation number. The name of the ELEMENT is placed first. Then the word HYDRIDE is written. It is preceded by the prefix mono-,di-, tri-, tetra-, etc ..., which indicates the number of hydrogens in the molecule. (the prefix is deleted if there is no doubt),
