Question

The densities of the nuclei: \(^{24}_{12}Mg\), \(^{40}_{20}Ca\) and \(^{88}_{38}Sr\),

• A. Have increasing trend
• B. Have decreasing trend
• C. Remain same
• D. None of these is correct

Hint:

The density of atomic nuclei does not vary much with changes in the atomic mass, as nuclear densities remain quite constant across various elements.

Answer 1

The Correct Option is C

The densities of the nuclei, such as \(^{24}_{12}Mg\), \(^{40}_{20}Ca\), and \(^{88}_{38}Sr\), remain approximately constant across different elements, even though their atomic masses and numbers differ. This phenomenon can be attributed to the nuclear packing inside the nucleus, which remains stable as the nucleus size increases with increasing mass.
Thus, despite differences in atomic number and mass, the density of these nuclear substances remains the same across these isotopes.
