The Correct Option is B
Solution and Explanation
The question relates to nuclear properties as the mass number, Aincreases.
1. Volume: As A (the number of nucleons) increases, the volume of the nucleus also increases because there are more protons and neutrons.
2. Density: The nuclear density is approximately constant for all nuclei. This suggests that the nucleus is uniformly packed and does not depend significantly on the number of nucleons.
3. Mass: As A increases, the mass of the nucleus also increases because there are more nucleons.
4. Binding Energy: The binding energy is the energy required to disassemble a nucleus into its constituent protons and neutrons. It varies with the number of nucleons and is not constant.
So, the only quantity that does not change as mass A increases is: 2. Density.

- Assertion :
The binding energy of the nucleus increases with the increase in atomic number.
Reason :
Heavier elements have a greater number of non-radioactive isotopes than radioactive isotopes. - The half-life of radioactive radon is 3.8 days. The time at the end of which \(\frac{1}{20}th\) of the Radon sample will remain undecayed is (given log10e=0.4343)
