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..

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

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 ..

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..

The proton has an equal and opposite to the charge of an electron. So, the absolute charge of a proton is 1.6 x 10 -19 coulomb of positive charge. This being the smallest positive charge carried by any particle, it is taken as 1 unit positive charge. The relative cha..

The proton has a mass equal to that of hydrogen atom, which is equal to 1.67 x 10 - 2 4 g or 1.0073 amu while it has an unit positive charge of +1.602 x 10 -19 ..

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 calculate the charge on the nucle..
