What happens if Electron collide with proton? What happens if Electron collide with electron?
As we know Newton's third doesn't work for Electromagnetism. So, I had got two questions in my mind.

1. We know that Electrons always distract electrons. But, if somehow they collide what will happen?

I found a related question of above one in [Quora](https://qr.ae/pGOZgU).

>An incoming electron can instead make them both bounce away.
>
>Two free electrons will bounce off each other unless perfectly aligned. In which case, both explode and produce photon(s).

I agree with his first statement. But, I am in little bit of confusion of second statement. I know that if Electron and Positron collide than, they will form photons. 

But, none of his statement answers my question. 

2. What will happen if Electron and Proton collide? If attracts each other inside Atom. But, why they don't collide inside Atom? Is "boundary" of Nucleus pushing them away?

>depends on the energy of the electron. For low energies, a bound state will be formed due to electromagnetic interaction between the two. In the case of higher energy, the proton can be transformed into a neutron. ~ [Physics SE](https://physics.stackexchange.com/a/88064/311383)

How they can form neutron? And, what they meant by bound state? While electrons have positive and protons have negative charge. They should collide and vanish, shouldn't they? (Another problem arise when thinking of Thermodynamics : According to first law of thermo, energy can't be created nor destroyed. So, they have to form to another one if that so than, how they can form neutron? Is it mattering for charge?)
