The neutron has a mass which is significantly higher than the mass of a proton plus the mass of en electron. So the electron stays as near as possible to the proton, but it cannot do anything with it. | |

| Mar 31, 2016 at 3:14 | comment | added | user5764 | Firstly, electrons don't switch between particles and waves; that's a major misconception. Electron is neither wave nor particle. Waves are not real but are of mathematical construct; they impart probability amplitude of finding the electron at a certain coordinate at a specified time. When you measure, you are collapsing the wavefunction into Dirac-Delta function; even after a minute time-interval, the wavefunction again starts to evolve according to the Schroedinger's equation. Electrons don't move in orbits like solar system; we don't need centripetal force. | |
