# Is Lithium hydride, ionic or covalent bonding?

Ionic Bonding

#### Explanation:

Lithium and hydrogen are bonded together through ionic bonding.

Lithium is a metal; during ionic bonding, lithium loses an electron to become the ion ${\text{Li}}^{+}$. Hydrogen acquires an electron from lithium to become the ion $\text{H} {:}^{-}$.

When they react, they each share their single valence electron to make a bond between the two atoms. It is reasonably polar ($\text{EN"_"H} = 2.2$, $\text{EN"_"Li} = 0.98$), which is why it is an ionic compound.
