Solution
The escape velocity (the minimum velocity with which a body is to be projected so as to escape from the gravitational pull) on the surface of moon is very much less, less than the RMS velocity (Root Mean Square velocity) of the molecules of gas at the surface temperature of moon. Therefore the molecules will escape and therefore moon cannot hold an atmosphere.
