unstable nucleus with excess neutrons turns to protons, emitting electrons and electron antineutrinos,in this case protons stay in nucleus...is there any case where protons are also emitted ...

Beta minus decay is a type of radioactive decay in which a neutron in an unstable nucleus is converted into a proton, releasing an electron and an antineutrino in the process.
Beta minus decay plays a crucial role in the stability of atomic nuclei. It is responsible for the conversion of neutrons to protons, which can change the overall composition and stability of a nucleus. Additionally, beta minus decay is used in many nuclear processes, such as energy production and medical imaging.
Beta minus decay occurs when an unstable nucleus has too many neutrons compared to protons. In order to reach a more stable state, one of the neutrons is converted into a proton, releasing an electron and an antineutrino. This conversion changes the atomic number of the nucleus, but the mass number remains the same.
The rate of beta minus decay is affected by the number of neutrons and protons in the nucleus, as well as the strength of the nuclear force holding the nucleus together. Other factors may include the energy levels of the particles involved and the presence of other particles such as electrons or neutrinos.
No, beta minus decay is a spontaneous process and cannot be controlled or manipulated. The rate of decay is determined by the characteristics of the nucleus and cannot be altered by external factors.
