Does the uncertainty principle apply to protons?

If you wanted to study the QM behavior of a proton beam and a potential barrier you would most certainly have an uncertainty relation for the proton. More specifically the uncertainty relation does not hold for specific particles, it holds for kinematic variables associated with any particle.

What happens if you put an electron close to a proton?

So, when an electron approaches the proton, it begins to feel the repulsive force of the electrons of the proton and the electron will be scattered. But sometimes, the electron will join the proton’s electrons in an orbit and thus become a neutron.

Why does the proton exist in the nucleus uncertainty principle?

The explanation is as simple is that: the closer attracting particles (say, protons) are to each other and more negative is their potential energy, the more defined is their position. Due to uncertainty principle this means large uncertainty in momentum and thus is more positive their kinetic energy.

Why electron Cannot exist in the nucleus explain with the help of uncertainty principle?

Second reason that electron can not exist inside the nucleus is that experimental results show that no electron or particle in the atom possess energy greater than 4 MeV. Therefore, it is confirmed that electrons do not exist inside the nucleus. The uncertainty principle states that ∆x∆px < h/2pi.

Why is an electron attracted to a proton?

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.

How does the uncertainty principle rule out the possibility of electron being inside the nucleus?

we will prove that electrons cannot exist inside the nucleus. If this is p the uncertainty in the momentum of electron ,then the momentum of electron should be at least of this order, that is p=1.05*10-20 kg m/sec. Therefore, it is confirmed that electrons do not exist inside the nucleus.

Why can’t electrons exist in the nucleus?

An electron will only react with a proton in the nucleus via electron capture if there are too many protons in the nucleus. But most atoms do not have too many protons, so there is nothing for the electron to interact with. As a result, each electron in a stable atom remains in its spread-out wavefunction shape.
