Doubt in exercise about bond energy

[guiromero]

Hello,

I have a question about an exercise of an MIT online course:

"For two bonded atoms X and Y, a small eX and large eY will result in a bond energy (Ea-b) with a large __________ contribution."

Where e = electronegativity

 I have tried "electronegativty", "polarity", "strength" and "bond strength", but none of them are correct.

Could someone give me an idea?

Thanks a lot.

There are two basic types of bond for atom to atom.

Ionic and Covalent.

Take your pick ?

 

This appears to be homework and should be placed there please.
