electrons are NOT moving about the nucleus, this is a model peopled used a long time ago and which, by chance, for the simplest situations, yields a couple good results.
electrons do NOT have a trajectory, nor a precise location, they are "located around" the nucleus, and the probability to find them at a given spot is proportional to the square of the amplitude of their "wave function".
go to any chemistry web site, or do "wikipedia orbitals", and you'll have a lot of graphs showing you the shapes of those probability functions in 3D space.

Under normal circumstances the electrons can not stop moving around the nucleus because they are not allowed by Hiesenberg's uncertainty principle. Because then you would know the speed and location of the electron simultaneously. Electron is not a round ball like entity as generally depicted in the text books. It is more like a disturbance a hazy looking disturbance which can not be located. You can only talk about probability of its existence at a particular point. It lies somewhere between a wave and matter, infact it is both.
Further it is possible for electrons to come out of atom and move around. This is what makes your TV screen work.

Unless something is exciting the atom, the electrons relax into the lowest energy state allowed by quantum mechanics, which differs from the classical description in that this state has finite kinetic energy. There simply is no solution to the Schrodinger equation for the electrons' wave function which allows the electrons to "stop moving". Your answer, then, would depend on what law of physics replaces quantum mechanics since your hypothetical situation would disprove the latter.

IF that occurred, they would be attracted to the nucleus and all matter would explode....but it won't happen because of the physical forces of the Universe cause them to keep on moving. Even electrons cannot disobey physical laws.

This is possible when the no.of protons are finetly greater than the no.of electrons .In this case the columbic force balances them

A GOOD ONE AS FAR AS MODERN CALCULATIONS ARE CONCERNED
THE ELECTRON WOULD GO AND CRASH INSIDE THE NUC.
NOW WHY SHOULD IT HAPPEN???OR WHY NOT??
IF THAT HAPPENS WE SHALL COME UP WITHA NEW THEORY .... REMEMBER chemistry stands for truth!!!!
