The strong nuclear force is an attractive force that counteracts (or rather balances-out) the repulsive coulomb force.
Forces can be modelled by an exchange of particles between the involved bodies. I think the particle responsible for the strong nuclear force is the gluon.
In a nucleus there should be a balance of protons and neutrons; too many protons and the repulsive force will be too high, too many neutrons and there won't be enough glue to go round.

Which two forces are responsible for holding the atom together?
The nucleus consists of protons and neutrons. Inside the nucleus, there is an electrostatic force of repulsion between the protons. Those protons have positive charges, and like charges repel. Also acting in the nucleus is a force of attraction called the nuclear force. It provides the nuclear binding energy to keep the nucleus together. This nuclear force is a short range force, and is so strong that it will overcome the effect of the force of repulsion between the protons.
What fact makes scientists believe that a strong force must be present in order to keep the nucleus of an atom intact?
protons repel other protons.
Why number of neutrons greater than protons in heavier nuclide?
The extra neutrons are needed to keep the attractive strong nuclear force within the nucleus greater than the repulsive electromagnetic force of the protons in the nucleus. With heavy enough nuclei eventually this fails.
How protons in the nucleus attract electrons.?
Electrically the protons repel each other, right? So what keeps them united? The answer is that there is a stronger force between nucleons - protons and neutrons. This force is called the "strong force". The strong force between two protons is not strong enough to keep them together (against the electrostatic force); but if there are some neutrons present, the situation changes, because the strong force acts between protons, but also between protons and neutrons.
Is strong nuclear force responsible for radiation?
No, not quite. Radiation, or more specifically, radioactivity, is the instability caused by the competition between the strong nuclear force and the electromagnetic force. The weak nuclear force also enters into the picture as well. The strong force holds quarks together to form protons and neutrons. Residual strong force, or binding energy, holds protons and neutrons together to form atomic nuclei. This force is attractive, no matter what the charge of the particle. The electromagnetic force is attractive for oppositely charged particles and, of more importance here, repulsive for similarly charged particles. This means that protons tend to repel each other, but the strong force overrides the electromagnetic force. Well, sort of... Its a function of distance. The strong force weakens much more quickly as distance increases than does the electromagnetic force. This means that, as nuclei get larger, the electromagnetic force starts to win out. This "break even" point is for atomic number 83, bismuth. Every element starting at bismuth and going up is radioactive, i.e. unstable, because the nucleus is so large that the strong force can't keep up with the electromagnetic force. That's not the whole picture, of course, because even smaller nuclei are also radioactive. This is where the weak nuclear force enters into the equation. The weak force establishes interactions between protons and neutrons such that the ratio of protons to neutrons in a nucleus controls the stability, i.e. radioactivity, of the nuclide. Take carbon-12, for instance. It is stable. So is carbon-13. But carbon-14 is not. The ratio is wrong, and the weak force causes beta- decay, but that's a topic for another question.
Why is the strong nuclear in an atom?
As you may know, there is the electromagnetic force which basically states that opposites attract and that equals repel. This means that the protons would repel each other inside the nucleus thus destroying the nucleus. The strong force is the force that is emitted by the gluons in the neutrons to keep the protons from repelling and destroying the nucleus. It is extremely strong but that reason for which it does not bring the electrons towards the nucleus is because it has a very short range.

What keep the electron in motion around the nucleus to which it is attracted?
the inter nuclear force of attraction between the nucleus and electron keep it moving in a circular manner around the nucleus
Why is iron used for girders in buildings?
because it can not erode and it is strong and will keep the building stable
What is the importance of neutrons?
The neutron is important because it allows for the binding of protons together to create atomic nuclei heavier than hydrogen. It's that simple. Perhaps as a testament to the "single-use" theory of the neutron is that when a neutron in not bound in an atomic nucleus, it is unstable. It has a half-life of a bit less than 15 minutes (or about 886 seconds). It's as if the neutron exists only to be a nucleon, or nucleus former. Protons have a positive chnooooarge and repel each other. Only the presence of neutrons among the protons in the nucleus will let the structure become stable. This occurs in nuclear fusion following the conversion of residual strong interaction (strong force) into nuclear binding energy or nuclear glue to keep the structure stable. The proof of the pudding comes when we look at the Periodic Table. At the top end, we see that no stable isotopes of the heaviest elements exist. Yet many stable isotopes of different elements exist at the bottom and through the middle. Use the link below to read more about the neutron.
Are squids helpful?
Every animal helps to keep the food web stable and strong (except for humans).
What is helium2?
Helium-2 would refer to an isotope of helium with a nucleus consisting of just two protons and having two orbital electrons. However, no such atom exists in nature as the two positively charged protons repel each other more strongly than the nuclear strong force attracts them to each other. So, even if such a nucleus could be formed somehow, it would split apart very quickly. On the other hand, if you add a neutron to the two protons in the nucleus, then the nuclear strong force is sufficient to keep the protons from flying apart. This, together with two orbiting electrons, is the stable helium-3 atom. The most common isotope of helium is helium-4, with two protons and two neutrons in the nucleus, and two orbital electrons.
