Question

What purpose do neutrons serve in the nucleus ? What happens if there are too many or too few neutrons?

Answer 1

These nuclei with different numbers of neurons are called isotopes

Answer 2

neutrons' main function is to attract each other and keep the nucleus of an atom intact. a nucleus will become unstable if there are too many or too few neutrons in it.

Step-by-step explanation:

too many= it will undergo beta decay (the neutrons will changes into proton)

too few= there will be an imbalance between forces which leads to nuclear imbalance
