How does an ionic bond affect the overall electronegativity of a molecule?

[Donovan McGraw 2C]

hi,
In class a few weeks ago we talked about the difference between electronegativity. There is a trend that can determine the type of bond. If the difference in electronegativity is >1.7, the character of the bond will be ionic, anything less covalent.

I agree with the first poster about how to determine bond type. But I think you mean after the bond was formed.
So bonds reduce the electronegativity of the entire molecule. Ionic bonds distort electron clouds so that anions do not hold onto them as strongly. It somewhat redistributes charge and "balances" the molecule which means less electronegativity.
