Q. Consider the following statements S1 : The nuclear force is independent of the charge of nucleons S2 : The number of nucleons in the nucleus of an atom is equal to the number of electrons in the atom S3 : All nuclei have masses that are less than the sum of the masses of constituent nucleons S4 : Nucleons belong to the family of leptons while electrons are members of the family of hadrons Choose the correct statement(s) from these
A) S1 only
B) S1 and S4
C) S2, S3 and S4
D) S1 and S3
Explanation
(d) The number force is charge independent
No. of nucleons = No. of protons + no. of neutrons = Mass number
All nuclei have masses that are less than the sum of the masses of its constituents. The difference in mass of a nucleus and its constituents is known as mass defect.
Nucleons belong to the family of hadrons while electrons belong to family of leptons
