Question

Explain the term nuclear isomers?

✓

Answer

The nuclides with the same number of protons $(Z)$ and neutrons $(N)$ or the same mass number $(A)$ which differ in energy states are called nuclear isomers.
In this, the isomer of higher energy is said to be in the metastable state which is represented by writing $“m”$ after the mass number.
e.g. Nuclear isomers of cobalt can be represented as, $^{60m}Co$ and $^{60}Co.$
