|
|
|
Exchange forces
|
|
|

Explanation:
Detailed explanation-1: -Nuclear forces hold together neutrons and protons in the nucleus.
Detailed explanation-2: -There are three forces at work inside the atom: electromagnetic force, strong nuclear force, and weak nuclear force. electromagnetic force is a force of attraction or repulsion between all electrically charged particles. Excess, or residual, strong force holds together protons and neutrons in the nucleus.
Detailed explanation-3: -Remember, the nucleus contains neutrons and protons. The neutrons are electrically neutral, and so the electric force won’t hold them in. Furthermore, the protons are all positively charged, and so they all repel each other.
