What evidence suggests that nuclear forces have a powerful force of attraction?

∙ 10y ago
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.

∙ 10y agoIf nuclear forces did not have a powerful force of attraction, the component protons in a nucleus would fly apart. Therefore, the existence of solid matter in the universe, such as you or me, is the prime evidence that nuclear forces have a powerful force of attraction.

∙ 10y agoThe exchange particle for the strong nuclear force is the pi meson. It has been produced by high energy collisions in particle accelerators, and detected by means of cloud chambers and bubble chambers. There is also very persuasive indirect evidence for the existence of the strong nuclear force, insofar as no atomic nuclei other than hydrogen could exist without that force, given that positively charged protons repel each other, and would not remain in close proximity in an atomic nucleus unless there was some force stronger than the electromagnetic force, holding them together.

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).
Use nuclear in a sentence?
It was a nuclear bomb. Everyone was afraid of a nuclear bomb. The nuclear power plant malfunctioned. The Cold War was about fear of nuclear attack.
What do you mean by nuclear accidents and can you explain two basic types of nuclear weapons?
A nuclear accident is the unintended release of nuclear radiation into the environment, such as damage to a nuclear reactor or to a nuclear weapon (plane crash carrying nuclear bombs, etc). The two basic forms of nuclear weapons are fission and fusion weapons.
Is nuclear harmful to people?
I'm pretty sure nuclear has a bad affect on humans. It really depends on what you mean by Nuclear. If you mean Nuclear Energy, no. It is vital. If you mean Nuclear Waste, yes. It is deadly. If you mean the Nucleus of an atom. It is part you you.
Does a bomb produce gamma rays?
Conventional bombs (dynamite, TNT, etc.) are not powerful enough to produce gamma rays. Gamma rays are only produced in a nuclear bomb or a thermonuclear (hydrogen) bomb where nuclear reactions take place.
Scientific evidence suggests that magnesium is formed by stars during?
Nuclear Fusion
What is some evidence that suggests that a nuclear reaction is occurring rather than a chemical reaction?
Beacause they are very alike & Then They Get Wild
Scientific evidence suggests that magnesium is formed by stars during what?
During the life cycle of massive stars, when carbon fuses to form neon and magnesium.
How powerful are nuclear weapons?
The most powerful.
What is the Rhino nuclear missile?
a VERY powerful nuclear weapon i think its the most powerful one
Are volcanoes are more powerful then nuclear weapons?
volcano weapons are more powerful than nuclear volcanoes
Is an bomb or a nuclear weapon more powerful?
If by "bomb" you mean a conventional explosive weapon, then the nuclear weapon is more powerful.
How much more powerful between chemical and nuclear reactions?
A nuclear reaction is much powerful than a chemical reaction.
Is nuclear energy from mars?
No evidence of this
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
In may 2008 US signed nuclear pact with which powerful nuclear country?
India
What are the main types of nuclear energy?
The two types of nuclear energy are nuclear fission nuclear fusion. In nuclear fission, the nuclei of the atoms are split. In nuclear fusion, as the name suggests, the nuclei of the atoms are joined together.
