why should the electron be in motion
Answers
Answer:
First of all according to quantum mechanics, electrons don't orbit around the nucleus in fixed orbits just like the planets in our solar system. Your question can be answered using uncertainty principle. ... It is for that reason that electrons have to be in continuous motion.

One of my students asked me, "Why does the electron move at all?" I admitted I didn’t know and would like to find out for myself and for her. Thanks

Awesome question! (Give your student my compliments for thinking it up!) Naturally, one would think that because protons are positively charged, and electrons are negatively charged, the two should attract and stick together. The reason that doesn't happen can't even begin to be explained using classical physics. This was one of the key mysteries that were cleared up right away by the invention of quantum mechanics around 1925.
The picture you often see of electrons as small objects circling a nucleus in well defined "orbits" is actually quite wrong. As we now understand it, the electrons aren't really at any one place at any time at all. Instead they exist as a sort of cloud. The cloud can compress to a very small space briefly if you probe it in the right way, but before that it really acts like a spread-out cloud. For example, the electron in a hydrogen atom likes to occupy a spherical volume surrounding the proton. If you think of the proton as the size of a grain of salt, then the electron cloud would have about a ten foot radius. If you probe, you'll probably find the electron somewhere in that region
