Nuclear Stability and Neutron/Proton Ratio
neutrons number against the atomic number for a range of stable nuclei Nuclear Stability and Neutron/Proton Ratio - It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stable nuclide..
Discovery of Neutrons
The whole mass of an atom is due to the nucleus, which means that the nucleus must contain protons equal to the mass of the atom. As the number of protons is equal to the atomic number, the atomic mass should be equal to the atomic number. But for all atoms except hydrogen the ..
Discovery of Neutrons
Search for the missing particle - Although Rutherford's model was enormously successful at explaining the scattering of alpha particles, there was a problem when the experimental data were used to calculate the mass of the nucleus. From the results of the scattering experiments, it was possible to ..
