Question

Why do both ionization energy and electronegativity both increase when an atom is smaller? *

A. The positively charged electrons are less attracted to the positively charged protons in the nucleus.
B.The negatively charged electrons are more attracted to the neutrons in the nucleus.
C. The positively charged electrons are more attracted to the negatively charged protons in the nucleus.
D. The negatively charged electrons are more attracted to the positively charged protons in the nucleus.

Answer 1

Both depend on the attraction of electrons - electronegativity deals with attraction of bonded electrons, ionization energy deals with the attraction of an atom's own valence electrons. More protons and a smaller atomic radius will increase both.
Hope this helps you find the answer
