Hi!

Considering the bond between two atoms A and B. How can i determine if this bond is ionic or covalent? As far as i remember, there is a number, above this number, is a ionic bond, or below, i don't remember. I believe it is binding energy between atoms, but i don't remember how calculate this.
Could you guys help me to do it?
