Electron can never fall into the nucleus as long as it revolves in the same shell,since it is not losing energy.Energy can be loosed by an electron when it jumps to another shell. When angular momentum is zero it denotes that e- can be in only 1 sub-shell i.e s sub-shell,so as long as the e- remains in s sub shell it will not looses its energy and cannot fall into the nucleus.
