Electronegativity is determined by how strongly an atom can attract electrons in a bond. The two main factors are the effective nuclear charge (more protons increase the pull) and how close the bonding electrons are to the nucleus (shorter distance strengthens the attraction). The option that mentions both the number of protons and the distance between electrons and the nucleus best captures these determinants, so it aligns with why some elements pull electrons more strongly than others. Neutrons don’t affect the positive charge of the nucleus, electron mass doesn’t influence the nucleus’s pull on bonding electrons, and environmental temperature doesn’t change the intrinsic attraction of the nucleus to bonding electrons.
