. Thus the relative mass of such a particle = 1 amu and the absolute mass = 1.6 x 10 - 2 4 g. Because of their electrical neutrality, these particles were called neutrons We are now in a position of explain why the atomic mass of carbon is 12. It is now known that the carbon ato..

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

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 ..

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 ..

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..

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..

The diameter of a proton is about 1 × 10 -12 mm. Identify the standard form. => 0.000000000001 or 12000000000 or 100000000000 or 10000000..
