How are ionization energy and electronegativity related to each other?

Ionization energy: the energy required to remove an electron from a neutral atom. Electron affinity: the energy change when a neutral atom attracts an electron to become a negative ion. Electronegativity: the ability of an atom in a molecule to draw bonding electrons to itself.
A.

When ionization energy increases does electronegativity increases?

Likewise, since the atomic radius generally decreases as one goes left to right within a period, the force of attraction increases and the ionization energy increases. Electronegativity is a relative measure of the force of attraction between an atom and the electrons it is sharing in a bond with another atom.
B.

What is the difference between electronegativity and ionization energy?

These properties are basically the inverse of each other. Electronegativity is the tendency of an atom to attract an electron and make it a part of its orbital. Ionization enthalpy, is the energy required to remove an electron from an atom. In other words, more electronegative atoms have high ionization enthalpies.
C.

Which element has the highest ionization energy and electronegativity?

Thus, fluorine is the most electronegative element, while francium is one of the least electronegative. (Helium, neon, and argon are not listed in the Pauling electronegativity scale, although in the Allred-Rochow scale, helium has the highest electronegativity.)

  • Why does electronegativity increase from left to right within a period?

    The positively charged protons in the nucleus attract the negatively charged electrons. As the number of protons in the nucleus increases, the electronegativity or attraction will increase. Therefore electronegativity increases from left to right in a row in the periodic table.
  • Why does fluorine have a higher ionization energy than I do?

    Fluorine has a higher ionization energy because it is in a lower energy level and does not receive the same intensity of shielding as Iodine. Thus Fluorine has a stronger nuclear force on the surrounding electrons and require more energy to remove electrons.
