Match the column: — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Isotopes are atoms with the same number of protons but different neutrons (A $\to$ R). Isotones have the same number of neutrons but different protons (B $\to$ Q). Isobars have the same mass numbers (C $\to$ P). Isodiapheres have the same difference between neutrons and protons, i.e., excess neutrons (D $\to$ S). Therefore, correct answer is A-R; B-Q; C-P; D-S.
