The IUPAC nomenclature of the compound LiAlH4 is "lithium tetrahydridoaluminate (III)". In this name, "lithium" is listed first since it is more electropositive than aluminum. The prefix "tetra" indicates that there are four hydrogen atoms in the compound, and "hydrido" is used to specify that each hydrogen atom is acting as a hydride ion, which has a -1 charge. The Roman numeral "(III)" indicates the oxidation state of aluminum, which is +3 in this case.
