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.

∙ 13y agoThe strongest force in the cosmos so far observed. This will be 10 ^40 times larger than the gravitational force. This nuclear force is not a fundamental force but only a secondary force. This exists because of transaction of sub elementary particles named as mesons in between the nucleons present in the nucleus. This was suggested by Yukawa.

∙ 9y agoNuclear force holds the positive protons and neutral neutrons in the nucleus together in the nucleus of the atom. The nuclear force has to be balanced with electromagnetic force.

What evidence suggests that nuclear forces have a powerful force of attraction?
Many atoms have nuclei consisting of several protons packed into an extremely small volume. Each proton has a positive charge, and since positive charges repel each other, the theory of electromagnetism says that these nuclei must not exist in a stable state. The fact that they do indeed exist leads us to believe that there is a force holding the protons together which must be stronger than the electromagnetic force. We call this force the strong nuclear force. In summary, the fact that protons are held together in nuclei despite their electric repulsion is evidence that there is a force (called the strong nuclear force) which is stronger than their electric repulsion.
The force of gravity the electromagntic force the strong nuclear force and the weak nuclear force are?
The four known basic forces in the universe are the gravitational force, the electromagnetic force, the strong force, and the weak force.
What is Non-contact force?
A non-contact force is any force applied to an object (or body) by another body that is not in direct contact with it. examples; Gravity, Magnetism or nuclear forces. hope this is of some help to you, Courtney - it is gravitational forces, electromagnetic force, strong nuclear force and weak nuclear force... get it!!! by Lachlan Cowan electromagnitism is the same as magnitism but it can be controlled.
Classification of forces?
There are four major types of force called as universal or fundamental forces of nature. They are: 1. Gravitational Force 2. Electromagnetic Force 3. Strong Nuclear Force 4. Weak Nuclear Force
Which intermolecular force is the weakest?
If you are asking about bonds of attraction between separate molecules, there are two kinds: dipole-dipole attraction and London dispersion force attraction. Dipole-dipole attraction is the stronger of the two, because the molecules in this case are polar, meaning that electrons are more often clustered at certain spots on the molecule and rarified at the opposite end, resulting in a greater charge on both ends (London dispersion forces are the weak forces of attraction between nonpolar molecules during random, fleeting moments of polarization). These forces are not to be confused with ionic attraction (which is attraction between ions, not molecules) and covalent bonds (which are the forces holding the individual atoms in a molecule together), both of which are stronger than any intermolecular force of attraction (with covalent bonding being the strongest of all bonds at the chemical as opposed to the nuclear level). Keep in mind, though, that the exact strength of attraction varies depending on the electronegativities of the different atoms in the molecule (but the weakest polar molecular bonds are, by definition, stronger than the strongest nonpolar molecular bonds).
What force pulls electrons and proton together?
Electrostatic force
What holds the nucleus and electron cloud together in an atom?
strong nuclear force. The nucleus is held together by both the strong nuclear force and the weak nuclear force. The electron is bond to the nucleus by electro-static forces.
What is proton-proton attraction?
actually, two positive (-ve)charges attraction is should not be occur but due to nuclear force of attraction two protons are bound to each other
What is the reveal the force that holds the nucleus together?
It is the strong attraction, or strong nuclear force, that holds the nucleus together within the atom.
Is the nuclear force a force of attraction or repulsion or both?
It is only attractive in nature. I am not sure which nuclear force you talk about. Electrical forces of the nucleus are repulsive to the positively charged. There are "strong forces" and the like which are attractive.
How proton held togetehr in nucleus as they have positive charge?
The strong nuclear force causes an attraction between them that holds them together.
What is the force that pulls objects toward each other called?
That can be gravity, electrostatic force, magnetic force, or strong nuclear force. As it's described in the question, the only thing we know for sure is that it's a "mutual force of attraction".
What force determines chemical properties?
The main force that determines the chemical properties of an atom is nuclear force. There are other forces included like electrostatic force and force of attraction among others.
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 is the force of attraction between two object s?
On the scale of things we can see, it's either gravitational or electrostatic. On a much smaller scale, it could be either the strong or weak nuclear force.
Which of the two has more force of attraction helium or oxygen?
Oxygen will have more force of attraction
The force that pulls objects toward each other is called?
That can be gravity, electrostatic force, magnetic force, or strong nuclear force. As you've described it in the question, the only thing you can call it for sure is "mutual force of attraction".
