Why protons and electrons do not collapse and cancel?

According to Physics opposite charges always attract But in an atom the distance between nucleus and electrons are small then why electrons didnt combined with protons? protons and electrons have opposite charges.But why they didnt combined each other?

Asked Gowtham

KS Samy answers:

“Good question,, both sub-atomic particle have certain mass and energy,, we also know that it,, there is electrons revolved an nucleus and their corresponding energy level,, so that it don’t care their charges.. only arrange respect that energy,,,,

the minimum distance between nucleus and orbital electron have minimum energy, as well as large distance it as more energy.”

Electron behaviour

An increase in energy level from E 1 to E 2 re...

Why an electron in level N when it gain energy it go to a higher energy level , why not going to a lower energy level , considering that word “higher” and “lower” refers to no of energy level but the energy of the energy level decrease as we go away from nucleus so an excited electron that gain an additional energy transfer to a higher energy level in no but lower in energy so why the electron doesn’t from its level to a lower energy level in no but higher in energy so the new energy level can bear the energy of the excited electron ?
(Moumen asks)
The question is not very clear. If you can explain it further, it will be better to discuss here.
