SUMMARY

During beta emission, a neutron decays into a proton and an electron, with the electron escaping as a beta particle while the proton remains in the nucleus. This phenomenon occurs because the strong nuclear force, which binds protons and neutrons together, is significantly stronger than the forces acting on the electron. The time required for the proton to interact with another nucleon through meson exchange is much shorter than the time it takes for the electron to escape, resulting in a higher probability of the proton remaining bound to the nucleus. Additionally, the antineutrino carries off excess momentum, further ensuring the proton's retention within the nucleus.

during a beta emmision in which a neutron brakes up into a proton and an electron the electron escapes as a beta partice but the proton doesn,t escape and remains with the nucleus why so![?] [?]

Now this occurs because during this process the time taken is roughly 100 times the time taken for a meson to exchange between 2 hardons so according to probabilaty there are great chances that some other nucleon from the nucleus will excange a meson with this newly created proton so this proton will come under the influence of nuclear binding force and thus won't escape but there is no such case with the elctron creatd so it will tunnel and escape.

You're missing one of the players in beta emission: the antineutrino. This baby carries off the extra momentum so the proton doesn't have to.
 


The reason why the proton does not escape during beta emission is due to the strong nuclear force that holds the nucleus together. This force is much stronger than the electromagnetic force that holds electrons to the nucleus. During beta decay, a neutron in the nucleus breaks up into a proton and an electron. The electron escapes as a beta particle because it is not bound to the nucleus by the strong nuclear force. However, the proton remains bound to the nucleus due to the strong nuclear force and does not escape. This is because the time taken for the proton to interact with another nucleon through the exchange of mesons is much shorter than the time taken for the electron to escape. Therefore, there is a higher probability for the proton to interact with another nucleon and remain bound to the nucleus. This is why the proton does not escape during beta emission.
