How is the size of a nucleus experimentally determined? Write the relation between the radius and mass number of the nucleus. Show that the density of the nucleus is independent of its mass number.
Answers
Answer:
Nucleus: It was first discovered in 1911 by Lord Rutherford and his associates by experiments on sacttering of α-paticles by atoms. He found that the scattering result could be explained, if atoms consists of a small central massive and positive core surrounded by orbiting electron. The experimenbt results indicated that the size of the nucleus is of the order of 10−14 meters and is thus, 10,000 times smaller than the size of atom. It there are N neutrons in the nucleus, then the number of protons and neutrons is given by
A=Z+N
A→Mass number
N→neutrons
Z→Protons
Actually mass nunber is integer closest to the nuclear mass.
