Nucleus: Practice Problem & Solution

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Nucleus. Understanding the underlying formula is key to arriving at the correct answer below:

The number of neutrons in $ _{6}C^{13} $ is $ 13 - 6 = 7 $. The number of neutrons in $ _{7}N^{14} $ is $ 14 - 7 = 7 $. Nuclei with the same number of neutrons are called isotones.
