Hydrogen
Question
Wired Faculty App

Arrange the following:
LiH, NaH and CsH in order of increasing ionic character.

Answer

Ionic character. The order of increasing ionic character is LiH < NaH < CsH.
Reason: Since electronegativity decreases as we move down the group from Li to Cs (Li > Na > Cs), therefore the ionic character of their hydrides also increases in the same order.
LiH < NaH < CsH
