Which factors affect electronegativity?

A. Atomic radius and number of unshielded protons

B. Density of the element and atomic radius

C. Number of electrons and atomic radius

D. Number of unshielded electrons and density of the element

I believe d is the correct answer

A-Atomic radius is indirectly proportional to the electronegativity. An increase in electronegativity leads to a decrease in atomic radius.

Explanation:

Electronegativity is used to measure the strength of electrons bonding to atoms.

Other factors include, nuclear charge and number of electrons present in an atomic shell.
