Question

As nuclear charge decreases, electronegativity :

• A. increases
• B. decreases
• C. decreases and then increases
• D. increases and then decreases

Answer 1

The correct option is B decreases

Electronegativity is determined by factors like the nuclear charge (the more protons an atom has, the more "pull" it will have on electrons) and the number/location of other electrons present in the atomic shells. As nuclear charge increases, electronegativity increases.
