- Protons and electrons stick to each other as much as they can, but kinetic energy and quantum mechanics keep them from holding still. Protons and electrons are attracted to each other because the positive electric charge of the proton is attracted to the negative charge of the electron.

Dec 15, 2018 · Under extraordinary conditions, protons do stick to electrons. The high pressure within a neutron star forces electrons and protons to react to form neutrons. Free neutrons don’t last very long.

Nov 1, 2009 · You can cause - if at very high pressures - electrons essentially to react with protons and turn into neutrons, and this is what happens in neutron stars. A neutron actually isn't stable just lying around in the atmosphere, or in a vacuum.
Feb 22, 2016 · Not only are electrons attracted to protons, electrons radiate away energy when accelerated. A classical electron in orbit around a proton should spiral into the nucleus in a small fraction of a second.
Nov 6, 2019 · The positively-charged protons repel each other and aren't electrically attracted or repelled to the neutral neutrons, so you may wonder how the atomic nucleus sticks together and why protons don't fly off.

The strong force is one of the four fundamental forces. The other three are electromagnetism, the weak force, and gravity. Particles need to be very close to one another to feel the strong force, but at a distance of one femtometer (10−15 m), the strong force is 137 times more powerful than electromagnetism, a million times stronger than the weak f...
Consider an atom: Electrons bear a negative electrical charge, so they are attracted to the protons in the atomic nucleus. But, electrons are tiny and move very quickly. They fall around the nucleus, much like a satellite falls around Earth. It’s theoretically possible for electrons to even pass through the nucleus, but they can’t stick. While the ...

The positive charge on a proton is equal in magnitude to the negative charge on an electron.
