Why electron do not collide with protons?

Answer 1

Electrons and protons do interact with each other in that the electrons are pulled towards the positively charged nucleus of the atom (positive attracts negative). Because of the force generated from this interaction, energy is required to remove an electron from an atom (ionization energy).

The electrons of an atom are arranged into shells of varying energy around the nucleus and can interact with electrons in other elements to form bonds that can be covalent or ionic.

Answer 2

A particle will annihilate with its antiparticle. An antiparticle is the opposite of the particle in all respects - not just the electric charge. The antiparticle of an electron is an anti-electron, also known as positron; the antiparticle of a proton is called an anti-proton.

Answer 3

Normally, atomic particles are kept separated by their repulsion of each other. Still, electrons (negative charge) and protons (positive charge) are ATTRACTED to each other. So they would, in effect, try to get closer to each other.

However, sub-atomic particles are NOT like little ball bearings -- when they get close to each other they do NOT collide. For these two particles, they actually don't do anything at all when they get close. Leptons (electrons, neutrinos) simply do not interact with hadrons (protons, neutrons) in our Universe, other than the electro-magnetic interaction. In our Universe, an electron within the electric field of a nucleus will go into one of a few permitted energy states, and stay there until some interaction causes it to go into another permitted state. If, while in this permitted state, it gets close to the nucleus, it simply exists there for a short time -- with no interaction with the nucleons there -- and then heads to another location.

Answer 4

1st answer:

Because in an atom, the number of electrons equals the number of protons, so positive and negative charge are equal so they cancel out each others effect and attain equilibrium.

2nd answer:

The above might apply to other electrons which come in addition to the electrons of the the neutral atom. But the questions concerns the latter. These are indeed attracted by the protons(!) of the nucleus. That's why they stay there and don't "go away".

In the "classical" Rutherford-Bohr model, the attraction is compensated by the centrifugal force arising from orbital motion around the nucleus.

But this model is not realistic. In reality, to explain subatomic phenomena correctly, equations of quantum mechanics have to be used. Point-like electrons are to be replaced with probability distributions, which are found as solutions from Schrödinger equations. The probability to find an electron is indeed growing as the distance from the nucleus decreases.

Answer 5

Electrons in an atom are similar to Earth in our solar system. The electrons are moving fast enough to not be pulled in by the protons, but slow enough that they can't escape from the atom. Creating elliptical patterns similar to planets.

Answer 6

In short: The question is ill posed, since they areattracted.

Answer 7

no electrons not attract protons because the spin of electrons is very fast around the nucleus

Answer 8

They may stick if require conditions are available for example the formation of a neutron star.
