Why dont the quarks in neutrons annhialate?

In summary, even though the quarks in neutrons have opposite charges and should attract, they do not just fall into each other due to the strong force and the stability of groups of 3 quarks. The Heisenberg principle and degeneracy pressure do not play a significant role in this phenomenon.

The quarks in neutrons have opposide charges and therefore they should attract, but why don't they just fall into each other. Is it the Heisenberg principle or degeneracy pressure?

Protons & electrons attract each other, and they don't annihilate either. So that must not be the issue. Particles and anti-particles can annihilate.

There are quarks in protons that are of different charges as well, as in neutrons. So that must not be the issue either.

In fact, quarks of different colors can be strongly attracted to each other. Groups of 3 can be very stable. The most elementary of those are protons & neutrons. The strong force pulls them (the quarks) together so tightly that charge is not much of a factor.

1. What are quarks and neutrons?

Quarks are subatomic particles that make up protons and neutrons, which are found in the nucleus of atoms. Neutrons are made up of three quarks, specifically two down quarks and one up quark.

2. Why don't the quarks in neutrons annihilate?

Quarks are held together by the strong nuclear force, which is stronger than the force of repulsion between the quarks. This force is also responsible for holding together the nucleus of an atom. As long as the strong force is stronger than the repulsive force, the quarks will not annihilate.

3. Can the quarks in neutrons ever annihilate?

If the strong force were to suddenly become weaker or if the repulsive force were to become stronger, the quarks in a neutron could potentially annihilate. However, this is highly unlikely given the current understanding of the strong force and the stability of neutrons in our universe.

4. Why do quarks in protons not annihilate like they do in neutrons?

The difference between a proton and a neutron is that a proton contains two up quarks and one down quark, while a neutron contains two down quarks and one up quark. This slight difference in the arrangement of quarks results in the proton being stable, while the neutron is only stable when it is bound in the nucleus of an atom.

5. How are neutrons and protons able to stay together in the nucleus?

The strong nuclear force, also known as the strong interaction, is the force responsible for binding the quarks together in both neutrons and protons. This force is incredibly strong, making it nearly impossible for the quarks to break apart and annihilate each other.
