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 nuclides upto Z = 20, N = 20 i.e., the relat..

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.

Whenever a - particle is emitted a neutron is lost and a proton gained. Therefore the neutron/proton ratio is reduced by - radiation. When an - particle is emitted the nucleus loses two protons and two neutrons. Since there were ori..

While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well. If you recall from earlier lessons, Atomic number (Z) is th..

Atoms contain three fundamental particles namely electrons, protons and neutrons. Protons and neutrons constitute the nucleus whereas electrons are present in the extra nuclear region of the ato..
