Electron Collision: Proton & Electron Interaction

[xMonty]

What happens when a negatively charged electron interacts with a positive proton, do they annihilate like electron and positron and produce photons? (i know they can't collide in an atom but if they were fired from opposite sides).

 

[DrZoidberg]

Electrons and protons can merge into neutrons. That's what happens when a star collapses into a neutron star.

Hi xmonty-
Sometimes a proton in a radioactive nucleus can absorb an atomic electron, emit a neutrino, and become a neutron. This is called electron capture or K-capture. See
