Which one of the following statements about electronegativity is correct?

Atoms with high atomic masses usually have high electronegativities.

An atom with high electronegativity will have high ionization energy and high electron affinity.

A highly electronegative atom will have low ionization energy and high electron affinity.

The only factor that affects the electronegativity of an atom is its ionization energy.

Electronegativity of an atom increases with its atomic radius.
