NUCLEAR PHYSICS
NUCLEAR MODEL OF AN ATOM
According to Ruthford experiment on the basis of high energy electron scattering and the high energy neutron
1 All nuclei are positively charged. The magnitude of a positive charge is an integral multiple of the charge of an electron. This integer is Z is known as atomic number.
2. More than 99.9 percent mass of the atom is concentrated in very small volume of the nucleus because extra nuclear particles are very light.
3. The distribution of positive charge is uniform and spherical in shape with few exceptions.
6. The measurement of nuclear radii suggest that nuclear volume is directly proportional to total number of nucleons present.
V ∞ A
r3 ∞ A
r = r0 A1/3 where A is total number of nucleons (mass number ) r0 is constant of proportionality
