Question:
relation between volume of a nucleus to its mass number
Answer:
The nucleus of an atom contains nucleons: protons and neutrons.
The mass number (A) or nucleon number is the number of protons plus the number of neutrons.
Various types of scattering experiments suggest that nuclei are roughly spherical and appear to have essentially the same average density. Hence, we know that r = r0A1/3 where r0 = 1.2 * 10-15m
Assuming the nucleus is spherical, its volume is given by
V = 4/3∏r3 = 4/3 ∏ r03 A
Thus we can get volume in terms of mass number for the nucleus of an atom.
