Compound is said to be ionic if electron negativity difference between bonding atoms exceeds 1.7 .

Q. Electronegativity values of elements are given
$K = 0.8 G e = 1.8 H = 2.1 C s = 0.7$
$P = 2.1 Cl = 3.0 S = 2.5 F = 4.0$
Out of $K Cl, P H_{3}, G e Cl, H_{2} S$ and $C s F$ ionic compounds are

KCl , GeCl , CsF

KCl, CsF

$P H_{3}, H_{2}$ S , KCl , CsF

KCl , GeCl

Compound is said to be ionic if electron negativity difference between bonding atoms exceeds $1.7$ .
