Which pair of atoms has the highest electronegativity difference?
(Calcium's electronegativity is 1.0
Fluorine's electronegativity is 4.0
Hydrogen's electronegativity is 2.2
Sodium's electronegativity is 0.93)
F-F = 4 - 4 = 0
Ca-F = 4 - 1 = 3.0
H-F = 4 - 2.2 = 1.8
Na-F = 4 - 0.93 = 3.07
Hence, the highest electronegativity difference is in Na-F.
