Where Protons Come from?

Free protons are emitted directly from atomic nuclei

in some rare types of radioactive decay. Protons also result (along with electrons and antineutrinos) from the radioactive decay of free neutrons, which are unstable.

How are protons created?

Protons along with electrons and neutrons are the building blocks of atoms. One can obtain a proton by stripping an electron from a hydrogen atom because hydrogen consists of one proton and one electron. This is known as ionization. ... This is about the energy of the electron beam found in a television picture tube.

Where did protons and electrons come from originally?

Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei.
