strong force
A nucleus is stable if the electrostatic and strong nuclear forces balance out.
It becomes most stable when its nucleus is filled, not when it is filling it.
The process of removing an electron from a stable nucleus is called electron capture. In this process, an electron is absorbed by a proton in the nucleus, converting the proton into a neutron and releasing a neutrino. This results in a more stable arrangement of particles in the nucleus.
A stable nucleus is one which will not decay, whereas an unstable nucleus will decay at some point, which cannot be predicted as decay is a random process, by alpha or beta decay.
You can predict whether an isotope nucleus is likely to be stable by considering the ratio of protons to neutrons in the nucleus. Nuclei with a more balanced ratio of protons to neutrons tend to be more stable. Additionally, nuclei with magic numbers of protons or neutrons are also more likely to be stable.
The atoms having 2 protons only in nucleus is not stable but 2 protons with 2 neutron in Helium nucleus are very stable.
By definition. If it were stable, then it would not be radioactive.
Being radioactive, uranium is not a stable element.
No. In fact the largest stable nucleus of any atom in it's non isotope form is Lead at 82 protons
The greater the binding energy the more stable the nucleus is.
Change from unstable to stable nucleus.
Not very stable, that's for sure.
