Lithium hydride

Lithium hydride is an ionic compound made of lithium and hydride ions. It has a high melting point (around 688.7 °C), but lower than most ionic compounds due to less electronegativity difference than other ionic compounds. The chemical formula is LiH. It has a molar mass of around 7.95 g/mol, making it the lightest ionic compound.
