Question

How do electronegativity values relate to the charge of an atom?

Answer 1

They do not relate to the charge of an atom, but to the relative strength of attracting electrons.

Explanation:

The charge of an atom is determined by the number of electrons gained or lost through chemical interactions. Which elements are more likely to gain electrons and which ones will be more likely to give them up is measured by the electronegativity value. But, it does NOT predict or correlate with the resultant charge of an atom. That is determined by it electron configuration.
