Question

Why are the protons inside the nucleus held in gether instead of being repelles​

Answer 1

Since we know that like charges repel each other and the protons in the nucleus have equal and like charges, but they are held intogether instead of being repelled

Answer 2

Answer:

Yes they repel each other with a very strong force but the reason that they are held together is a force called strong nuclear force which is considered the strongest force as it overcomes the repulsion between protons.

however in atoms with a lot of protons like Francium the repulsion actually becomes so high that the nucleus 'breaks' or in other words the element shows radioactivity. But as far as smaller elements, more common elements are concerned the protons are held together by the strong nuclear force.
