Weak force holds neutrons together?

In summary, the neutron is held together by the weak force, which is responsible for its eventual decay. However, the strong force also plays a role in binding the quarks within the neutron and suppressing its decay. Free neutrons do decay, but the residual strong force within nuclei can prevent this decay from occurring.

I have been given the impression that the weak force is what holds the neutron together (preventing it from decaying to an electron and proton)
and that the neutron eventually decayed, despite this weak force, by 'tunneling out'

Is that right or am I way off?

The weak force is responsible for the decay. This decay is not suppressed - free neutrons _do_ decay.

The binding of quarks in the neutron is due to the strong force. The residual strong force which holds protons and neutrons together in nuclei _does_ suppress the decay of the neutron
 

Related to Weak force holds neutrons together?

1. What is the weak force?

The weak force is one of the four fundamental forces of nature, along with gravity, electromagnetism, and strong nuclear force. It is responsible for radioactive decay and plays a crucial role in the structure and stability of matter.

2. How does the weak force hold neutrons together?

The weak force is responsible for the process of beta decay, in which a neutron can transform into a proton, an electron, and an antineutrino. This process helps to stabilize atomic nuclei by balancing out the number of protons and neutrons.

3. What is the range of the weak force?

The weak force is the shortest-range fundamental force, with a range of only 10^-18 meters. This is much smaller than the other fundamental forces, which have infinite range.

4. Can the weak force be observed in everyday life?

Although the weak force is present in everyday life, it is not directly observable in macroscopic objects. It is only noticeable in the behavior of subatomic particles and the processes of radioactive decay.

5. How does the weak force differ from the other fundamental forces?

The weak force is significantly weaker than the other fundamental forces, with a strength about 10^-13 times that of the strong nuclear force. It also has a much shorter range and only affects particles with a left-handed spin, while the other forces do not have this restriction.
