Which has a higher frequency, a neutron or electron? Why?
DanielleElmas [232]
The electron, due to the way an electron orbits the nucleus of an atom. 

According to Quantum Mechanics, electrons do not really orbit the nucleus of an atom. In fact, the most tightly bound state, the 1s orbital, has no angular momentum at all. This would be the state with the most "kinetic energy" and yet there is no "orbital" motion at all in this state.
