Question

If neutrons exert only attractive force, why don't we have a nucleus containing neutrons alone?

Answer 1

Answer:

Neutrons don't exert any force they are neutral and they do not have any charge on them.

Protons and electrons have positive and negative charges respectively and thus provide attractive force against each other.

Answer 2

Explanation:

• Nuclear forces are the attractive forces that are short ranged, which acts between neutron-proton, proton-proton and neutron-neutron pairs.
• There will be strong nuclear forces between two protons and they also exhibit electrostatic repulsion among each other.
• When compared to the strong nuclear forces, the electrostatic forces have very less effect and they are long ranged.
• Thus, there will not be any importance of repulsive force in a nucleus when compared to the nuclear force that is strong and attractive.
• In other terms, there will be electron revolving around the atom’s nucleus. By the strong electrostatic force, these electrons are placed in their orbit, which is exerted by the protons that are there inside the nucleus.
• So, there will be neutrons and protons inside the nucleus.
