The lithium ion $\left(L{i}^{+}\right)$ and hydride ion  $\left(H^{-}\right)$  are isoelectronic ions. Which statement about these systems is true ?

$L{i}^{+}$  is a stronger reducing agent than $H^{-}$

More energy is needed to ionize  $H^{-}$than  $L{i}^{+}$

Radius of  $H^{-}$ is larger than that of  $L{i}^{+}$ 

Chemical properties of these ions are identical since they are isoelectronic
