Electrons are in constant motion around the nucleus because of?
The force that keeps an electron moving around the nucleus is the electric force. The balance of the electric force and the centrifugal force gives the quantum redshift.0= e^2zc/4pi r^2 -mcv/r cos(V) gives cos(V) = Alpha/n the redshift, where Alpha is the Fine Structure Constant 7.2E-3.
