Answer:
If the electronegativity difference is greater than 2.0, then the bond is ionic.
Explanation:
For ex:
Na has the electronegativity of 0.93
Cl has the electronegativity of 3.16
we subtract 3.16-0.93
We have 2.23 electronegativity difference between Na and Cl
because 2.23 > 2.0
therefore NaCl compound has an ionic bond.
