Question

Arrange F,Cl,and Br in order of their increasing first ionization energies.
A) F < Cl < Br
B) Cl < F < Br
C) Cl < Br < F
D) Br < F < Cl
E) Br < Cl < F

Quizplus · Accepted Answer

The ionization energy generally increases from left to right across a period of the periodic table. Thus, bromine (Br) has the highest ionization energy, followed by chlorine (Cl), and then fluorine (F). Therefore, the correct order is Br < Cl < F.
