Question

What is the role of neutrons in an atom?

Answer 1

Answer:

B) neutron keep protons apart so they don’t repel  each other

Explanation:

Neutrons are of almost same mass as that of protons mass or we can say it is slightly greater than the mass of proton

There is no charge on the neutrons as they are neutral and they resides inside the nucleus.

since nucleus is a small region where large number of protons and neutrons exists so in this small region protons must have large repulsion force between them but since this repulsion force is counterbalanced by the strong nuclear force between the neutrons and protons so here role of neutrons is to provide sufficient strong force to bound the nucleons together

so here correct answer will be

B) neutron keep protons apart so they don’t repel  each other

Answer 2

Hihi!

The correct answer is B) neutron keep protons apart so they don’t repel 
each other! The neutron also adds mass to the atom!
