Li has an ionization energy of 520 kJ/mol. F has an ionization energy of 1680 kJ/mol. Which of the following is a possible explanation for the trend?
OFlorine has strong attractive forces between the nucleus and the electrons. It takes more
energy to remove an electron from fluorine than lithium.
OEach electron on an atom has a set amount of energy. Since fluorine has more electrons,
then it will have more ionization energy than lithium.
OLithium has a smaller atomic raâius than fluorine. It takes less energy for an electron to be
added to the outer energy level on lithium than the outer energy level on fluorine.
Olonization energy increases down the periodic table and decreases across the periodic table
