As an atomic radius increases, what happens to the ionizaton energy?

• The ionization energy decreases the further the electron is from the nucleus due to additional energy levels

• The ionization energy increases the further the electron is from the nucleus due to additional energy levels

• The ionization energy decreases and then increases the further the electron is from the nucleus due to additional energy levels
