Nucleus of all the atoms except Hydrogen have two basic particles - Protons and Neutrons. Protons and neutrons rotate on their axis and produce magnetism. Two adjacent protons have revolution in opposite direction and nullified the effect of magnetism. Protons and Neutrons - the basic particles are not placed very close to each other - they have some space between them - large enough to take care of repulsion because of charge. Protons have positive charge and therefore protons can repeal each other, but they are not close to each other and they have Neutron between them as buffer. This makes nuclei stable.

The nuclear structure is explained in terms of the interactions between neutrons and protons (coloumb force between protons and residual strong force between protons and neutrons, which holds the nucleus together). Any absolute statement on the position violates the uncertainty principle.
A force which can hold a nucleus together against the enormous forces of repulsion of the protons is strong indeed.
The strong force between nucleons may be considered to be a residual color force.
We are not really done with studying the nuclear structure, even in terms of effective forces between nucleons. It is however true that we already reached an excellent level of understanding.

What remains to be done is really to understand to role of quarks and gluons in the nuclear medium. For instance, we have a good deal of hints pointing towards the fact that hadrons in the nuclear medium are not the same as free hadrons. The propagate differently. There is color transparency, nuclear shadowing, and many technical details (some of them very minute), but the mere fact that the neutron is stable inside the nucleus is already an excellent indication.

So overall, the picture is still the following (IMHO) : proton and neutrons in the nucleus are vey much alike orange and apples stacked together. Their "quantumness" is tiny enough so that we can apply semiclassical methods and get excellent results. The inherent quantum and extreme-relativistic nature of quarks and gluons inside hadrons however makes it very difficult to go beyond this simple picture, and in fact very little progress has been made since about Heisenberg was working on this problem

The protons are also together with the neutrons which are electrically neutral. Though the protons have the same charge, the neutrons also help them in binding them up together. The force which keeps all these protons and neutrons together is the Binding force.

The nucleons (neutron and proton) further consist of much smaller particles which gives neutron and proton opposite charges thereby making both types of particles to get stuck.

protons are made staying togeather not by the force of their charge, coz i n that case it would be able to add more and more protons into some atom. It's nuclear force.

As the protons are of same charge until then the are held together in neucleus because their is a different type of force exist in the neucleus known as the 'strong force'. it is the strongest force existing in the universe.
Forces in increasing order of their strength:-
1.gravitational force
2. magnetic force
3.electrostatic force
4.strong force
Strong force exist in neucleus becuse the protons are situated very close to each other so they generate this type of force

They all have the same charge, and they are held together by the "strong nuclear force".

PROTONS HAVE POSITIVE CARGE
