Question

$NaH$ is an ionic hydride. If true enter 1, else enter 0.

Answer 1

NaH is an ionic hydride. There is electronegativity difference betwen Na and H. Na loses an electron to form $N{a}^{+}$ ion and H gains an electron to form $H^{-}$ ion. The electrostatic force of attraction between cation and anion forms ionic bond.
