# Can a hydrogen atom sit still?

Can we take a single lone hydrogen atom (proton and electron?) and set it in one place and observe it staying there?

A neutron?

At least for spin-$\frac{1}{2}$ particles like protons and electrons this is not possible. A phenomenon called zitterbewegung is responsible for rapid motion of these particles. The frequency of these motions can be as high as $10^{21}$ hertz.
