Geeta got a doubt, ''Why does atomic nucleus contain proton and neutrons? Why can't electrons and neutrons be in it.'' Can you help to clarify her doubt? Explain.

Text Solution

Verified by Experts

Nucleus contains protons and neutrons inside it but not electrons and neutrons. If it would have happen, then
1) The alpha particles in the Rutherford's alpha particle scattering experiment would have not been deflected or scattered.
2) The idea of nucleus would have not been evolved because the mass of electron is negligible, it is most unstable.

Atoms are complicated than hydrogen have more than one proton in their nucleus. Let z stands for the number of protons in a nucleus. Also imagine that an atom loses all but one of its electrons so that it changes into a positively charged ion with just one electron.

Also imagine that an atom loses all but one of its electrons so that it changes into a positively charged ion with just one electron. Bohr.s formula for the energy levels of the hydrogen atom can easily be changed to apply to such ions. It becomes E_m = (-Z^2 e^4 m_e)/(8 epsi_0^2 h^2 n^2) , where m= mass of electron , e= change of electron, n = orbit number. The ionization potential of Het in ground state is
