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

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.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

lol for the pointsss
