The name of $LiH$ is "Lithium hydride."
Work Step by Step
1. Identify the positive ion, and name it. $Li^+$ is the positive ion. So, the first name of the compound will be: "Lithium." 2. Identify the negative ion, and name it. $H^-$ is the negative ion. This is a monoatomic anion; therefore, it will receive the element's stem name "hydr", plus the suffix "ide": "hydride" 3. Putting those two names together: Lithium hydride.
