Limiting the movement of the electron to an orbit is not impossible, as some American physicists have managed to 'catch' the external electron of a lithium atom in an elliptical orbit. Normally, the electron does not follow a certain trajectory around the nucleus.
It is more complex than this: normally the electron is found in an area called orbital. However, now physicists have forced an electron to follow a certain orbit, like planets orbiting the Sun. For physicists, the precise control of the electron allows the development of new laser manufacturing techniques.
