### Why are the dineutron and diproton unbound?

It is known that there is no diproton and dineutron nuclei. Does this mean that two protons or neutrons are not actually attracted to each other? Even if the attraction was weak, wouldn't it cause ...

### Stable Nuclei - Deviation from equal protons and neutrons

While studying the semi-empirical mass formula for nuclei, I came across an "asymmetry term" whose function, as far as I understand, is to build in the fact that nuclei "prefer" to have equal numbers ...

### How (if at all) can the neutron-proton ratio of stable atoms be explained under the nuclear shell model? [duplicate]

To begin where I did with this question, I was originally wondering about why the neutron-proton ratio is close to 1 for stable nuclei. The answer to my original question (as far as I understand it) ...

### Why is a nuclei with too many neutrons unstable? [duplicate]

I understand that a nuclei with too many protons is unstable as the electromagnetic repulsion becomes too strong to be balanced by the strong nuclear force. However in the case of there being too ...

### Quantised energy levels of the nucleus

We know that the atomic energy levels are quantised since the nucleus has a potential of its own and solving the Schrödinger equation we can see that. But in gamma emission we see that the origin of ...

### Strong nuclear force vs electrostatic repulsion between protons

Does the strong nuclear force balance the electrostatic repulsions between the protons or does it overcome the repulsion? I looked up on wikipedia and it says that the strong nuclear force is ...

### Asymmetry in p-p, n-n and n-p interactions

Why does the asymmetry exist between the proton-proton, neutron-neutron and neutron-proton strong interactions in the nucleus (which results in nuclei preferring equal numbers of neutrons and protons)?...
