Question 1 Which of the following factors contribute to the fact that the polarizability of helium is less than that of argon? Select all that apply. Helium's electrons are more tightly bound than those of argon, since they are closer to the nucleus. Helium's nucleus is smaller and the protons cannot move as far as those of argon. Argon has many more electrons that can adjust to an external electric field than does helium. Helium and argon are both inert gases and so do not...
