What will happen when a electron is kept near a proton ?
[electron] + [proton] => [hydrogen atom] + 13.6 eV
that happens naturally, without application of external
force. If they are "kept near" via application of external
force (high energy scattering), you'll eventually get
[electron] + [proton] => [neutron] + [neutrino]
The nearly massless neutrino moves away at near the
speed of light. A free neutron isn't stable, and after about
10 minutes:
[neutron] => [proton] + [electron] + [anti-neutrino]

Depends on what you mean by "near" and whether the proton
and electron have kinetic energy relative to each other.
Two things that might happen:
- the electron is bound and you get atomic hydrogen.
- the electron is captured, combining with the proton to create
a neutron.
I'm not sure what the conditions for that second thing are. It's
something that happens in radioactive atoms, but not perhaps
with free protons and electrons.
