Question

electronegativity of LiH show your solution

Answer 1

The ionic character of bond depends on electronegativity difference between two atoms. When the electronegativity difference is larger, the ionic character is smaller. On moving down the group of alkali metals, the electronegativity decreases from Li to Cs. Hence the ionic character increases in the order LiH<NaH<CsH.

Answer 2

Answer:

Less ionic character because ionic character of bond depends on electronegativity . Hence , down the group of alkali metals, the electronegativity decreases from Li to Cs.
