What makes certain atoms more electronegative?

Atoms with more protons tend to have higher electronegativity because it depends on the atomic number. Higher electronegativity means that electrons are pulled stronger towards itself. Therefore, if the positive nuclear charge is higher, more electrons are pulled closer.

The atoms of elements toward the right of a period (except for the noble gases) are more electronegative because they have more protons and the same amount of shielding compared to the other elements in the same period. Therefore, their nuclear charge is higher and it's easier for them to pull an electron to themselves. Also, they are closer to completing an octet than the other elements toward the left of the period.

The more protons the atom has, the more electronegative it is.
