Isotones are defined as atoms of different elements possessing the exact same number of neutrons. Gi — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Number of neutrons = Mass No. ($A$) - Atomic No. ($Z$). For ${}_{6}^{13}C$: $n = 13 - 6 = 7$. For ${}_{7}^{14}N$: $n = 14 - 7 = 7$. Both possess exactly 7 neutrons, making them isotones.
