Answer = Yes

Electronegativity value of sodium = 0.9

Electronegativity value of Chlorine =3.0

Difference = 3.0 - 0.9 = 2.1

Difference in electronegativity value = 2.1 which is more than 1.7 hence it forms ionic compound.

Electronegativity value of potassium = 0.8

Electronegativity value of Bromine = 2.8

Difference = 2.8 - 0.8 = 2.0

Since electronegativity difference is 2.0 which is more than 1.7, hence it will form ionic compound.
