What is a type of force that holds the nucleus of an atom together?

The nuclear force or nuclear binding energy holds anatomic nucleus together. (Some science teachers insist it's calledthe strong nuclear force, which is not quite correct.…) Nuclear binding energy is this nuclear force that overcomes therepulsive electrostatic force of the protons, which is trying topush the nucleus apart. The nuclear binding energy is created fromwhat is called mass deficit. When an atomic nucleus is fused, allthe protons and neutrons in that nucleus give up a small amount oftheir mass, and this mass is converted into the binding energy thatholds the nucleus together. And if you guessed that an atomicnucleus has less mass than the sum of the masses of its constituentprotons and neutrons, the nucleons, you would be correct. We sometimes call the binding energy nuclear glue, and it isderived from the stong nuclear force or strong interaction. Thatalso gives rise to another term used for nuclear binding energy,and that is residual strong force . The reason we say thatnuclear binding energy is derived from the strong interaction isthat the stong interaction actually holds individual protonsand neutrons together. It is the strong interaction that bindsquarks and gluons together into individual protons and neutrons.And it is in nuclear fusion that the strong interaction mediatesthe creation of the binding energy to hold a newly fused nucleustogether. Answer: Nuclear binding energy or residual strong force We know protons are all positively charged, and a fundamental lawof electrostatics is that like charges repel. But under extremeconditions, nuclear fusion can occur. Positive charges are forcedtogether with neutrons, and all of the particles undergo changes.Each particle gives up a small amount of mass, and this mass isconverted in to nuclear binding energy or nuclearglue. And it is this nuclear glue, what is called the residual strong force , that overcomes the repulsionbetween the protons and binds all the particles in the nucleustogether. At the extremely small distances between the protons, the bindingenergy is greater than the electrostatic repulsion trying to forcethe protons apart. This is true for elements up to those at theupper end of the periodic table. The heaviest elements experienceinstability because of the large numbers of protons in theirnuclei, and for the heaviest elements, there is no way a"permanent" nuclear arrangement can be made. The residual strongforce cannot act across these large nuclei to make them stable, andthey exhibit nuclear instability. This results in them beingsubject to radioactive decay. It is not entirely correct to say that the strong force holdsatomic nuclei together, as the strong force (strong interaction)actually holds individual protons and neutrons together. It doesthis by tightly binding the quarks and gluons that make them up. Itis the residual strong force that holds atomic nucleitogether. That is the source (through mass deficit) that createsthe nuclear binding energy or nuclear glue that acts to oppose theelectrostatic repulsion of the protons. You might be aware that thestrong nuclear force, along with the weak nuclear force, theelectromagnetic force, and gravity, are the four fundamental forcesin the universe. It is called, appropriately enough, the nuclear force. It goes by several names: strong force, strong nuclear force, andcolor force. They're all describing the same thing. Strictly speaking, the strong force is what holds quarks togetherin a hadron. The force that holds hadrons together is the residual color force. the strong nuclear force is created between nucleons by theexchange of perticles called mesons (changeless particles hadronsmade up of one quark and one antiquark).as long as the meson canhappen,the strong nuclear force is able to hold the participatingnucleons together . The nucleus is held together by the strong force . The electrons are held in the atom by the electromagneticforce Protons and neutrons are held together in the nucleus by thenuclear force, also known as the residual strong atomic force, alsoknown as residual binding energy. Strong atomic force (binding energy) holds quarks together to formprotons and neutrons. It is the strongest force in the universe,followed by a factor of about 100 by the electromagnetic force, andthen by many orders of magnitude by the weak atomic force, and thenby many many orders of magnitude by gravity. Since it is strongerthan the electromagnetic force, it easily overcomes the tendency ofthe up quark (charge +2/3) and down quark (charge -1/3) to repeleach other. Of course, all of this is a function of distance, so gravity hasthe most effect, when you consider distance, but in the range of asingle proton or neutron, the strong atomic force is king. What is left over from holding quarks together is called residualbinding energy, or simply, the nuclear force. The nuclear forceholds protons and neutrons together. While less than the force ofbinding energy, it is still more powerful than the electromagneticforce, so the protons with a charge of +1, though tending to repeleach other, still stick to each other. Well, its not quite that simple... In the distance of a proton or a neutron, there is no questionabout strength but, beyond that, the nuclear force degrades withdistance, as does the electromagnetic force. Interestingly thenuclear force degrades faster than the electromagnetic force... The ramification of this is that, for smaller nuclei, withexceptions noted below, the nuclear force wins out over theelectromagnetic force, and the nucleus is stable. This holds trueup to atomic number 82 - iron. Starting at atomic number 83 -bismuth - the electromagnetic force starts to win out over thenuclear force, simply because of the size of the nucleus, and thenucleus becomes unstable. As a result, no nuclide starting atbismuth and up is stable - they are all radioactive, while mostnuclides from iron on down are stable. The exception, as promised, is that we still have the issue ofproton to neutron balance. It turns out that there is an idealconfiguration, based on many things, which is beyond the scope ofthis question. Suffice to say that 80 of the first 82 elements,from hydrogen to lead, excluding technetium and promethium, have atleast one stable isotope. In an atomic nucleus, protons and neutrons are held in together bywhat is officially known as the strong nuclear force. The exchangeparticle by which this force manifests itself is the pi meson.
The strong nuclear force and the weak nuclear force act within thenucleus to hold it together.
the strong nuclear force (yes, this is it's real scientific name!)
Strong intermolecular bonds and the "strong force," or nuclear force.
The strong nuclear force.
The residual strong (or color) force.
The nucleus is held together by what is officially known as the strong nuclear force. Since the nucleus of all elements except hydrogen contains more than one proton, and all… protons repell all other protons (since they have positive electric charges, and like charges repell, as stated in Coulomb's Law) any nucleus other than a hydrogen nucleus would simply explode from electrostatic repulsion, if not for the strong nuclear force holding it together.
That is the strong nuclear force.
This is called the strong nuclear force, at close range it overcomes electrostatic repulsion between protons. This force had to be deduced from the stability of nuclei, but th…eoretical physicists are still trying to explain what it really is and how it works.
The strong nuclear force, also called binding energy, holds quarks together to form protons and neutrons. Residual binding energy, also called the nuclear force, holds protons… and neutrons together to form the nucleus of an atom. This holds true up to about atomic number 83 (bismuth), at which point the electromagnetic force, a repulsive force for protons, starts to overcome the distance barrier of binding energy and make the nucleus unstable. This makes the atoms starting at bismuth and above be radioactive. Additionally, the presence or absence of extra neutrons, i.e. isotopes, even in light nuclides, can, due to the weak interaction, makes the nucleus be unstable, and radioactive.
its proton and its nucleus will have two protons so its electron and atom
