Question

in order to have a conplete transfer of electron/s, the electronegativity difference of the two combining elements must be:
a. less than 1.9
b. Greater than 1.9
c. Equal to 4
d. Equal to zero​

Answer 1

Answer:

The rule is that when the electronegativity difference is greater than 2.0, the bond is considered ionic. So, let's review the rules: 1. If the electronegativity difference (usually called ΔEN) is less than 0.5, then the bond is nonpolar covalent.
