Question:

Which is the least polarizable gas among the following?

Options:

1. $\text{He}$
2. $\text{Ne}$
3. $\text{Kr}$
4. $\text{Xe}$

Solution:

$\text{HINT: Polarizability is directly proportional to the size of gas.} \text{Explanation:} \text{Polarizability usually refers to the tendency of matter, when subjected to an electric field, to acquire an electric dipole moment in proportion to that applied field.} \text{Generally, polarizability increases as the volume occupied by electrons increases. The relation between polarizability and atomic radii is "Polarizability } \propto \text{ atomic radii of the gas molecule".} \text{Among the gases given in options, the size of He is the smallest. Hence, it is the least polarizable.}$
