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..

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 ..

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 ..

A neutron is a particle having a mass equal to 1.67 x 10 - 2 4 g (hydrogen atom) and no electrical charg..

Since the atom is electrically neutral there had to be positively charged particles present in the atom to neutralize the negative charge of the electron..

These are slow moving neutrons. Slow moving neutrons are used to bring about the fission reaction. If we use fast moving neutrons, it will not be in contact with the fissionable material for sufficient time to bring about the fission reactio..

A proton can be thought of as a hydrogen atom that has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is for all practical purposes 1 a.m.u., the relative mass of a proto..

Since the atom is electrically neutral there must be positively charged particles present in the atom to neutralize the negative charges of the electrons. Goldstein experimentally proved the existence of protons in the ato..
