> neutrons described as a union of a proton and an electron based on masses
If you squish an electron and proton really hard, you'll get a neutron [1].

And a neutrino: https://en.wikipedia.org/wiki/Electron_capture
If I understand correctly, which I probably don't, this is what releases the final wave of neutrinos in a supernova.
