Question

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 have dipoles. Polarons require large surface areas on which to create polarizability, and argon has more surface area than does helium. Argon has more isotopes, and this spreads out the charge more.

Answer 1

The feefar that contribute to the fact that the polenizibility of helium is less than that of argon are • Netium elechons ce more tightly bound them those of argon, since they are close to the nucleus. Due to this er cloud can not be distort properly to show polenizibility Argon to an has many more electress that can adjust external . efectua fired the the day helium Polarons require large surface areas on which to Creek bolanizibility and angan and anyon has more surface thon does helivom As to both argon . and helium are nobel gases, the and I only interne forces play is the London - Dispersion force. The polemizibility depends how diffuse the elechen cloud is. 1. As the sle of the atom inenses from He to An, so does the elechring. Hence the size of e-cloud gets bigger from be to n. now, Polerisibility defends Stuface area of a noleate, As the surface area of the and er density is highe in An, so its polarizibility also higher than her
