Vedclass · Answer

(D) The polarizability of an atom depends on its size and the strength of the hold the nucleus has on its valence electrons.As we move down the group in the periodic table,the atomic size increases and the valence electrons are further away from the nucleus.Therefore,the valence electrons are more loosely held,making the atom more polarizable.Among the given options,$Xe$ has the largest atomic size and the lowest ionization energy,making it the most polarizable.

Which of the following noble gases is most polarizable?
