How do we know neutrons exist
WebApr 20, 2024 · The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron. There is also a maximum energy that each electron can have and still be part of its atom. Beyond that energy, the electron is no longer bound to the nucleus of the atom and it is considered to be ionized. WebNeutrons can exist on their own for an average of about 10 minutes, after which they decay via n → p + + e − + ν ¯ e. The neutron is (as its name suggests) electrically neutral, so it feels no electrostatic attraction to atoms.
