A
If both assertion and reason are true and the reason is the correct explanation of the assertion
B
If both assertion and reason are true but reason is not the correct explanation of the assertion
Why the mass of the nucleus is less than the sum of masses of the nucleons?
The mass number of a nucleus of an element is
Assertion:The whole mass of the atom is concentrated in the nucleus. Reason:The whole mass of the atom is concentrated in the nucleus Reason:The mass of a nucleus can be either less than or more than the sum of the masses of nucleons present in it.
The mass of an atomic nucleus is less than the sum of the masses of its constituents. Thus mass defect is converted in to
