It's thought that another one of these magic numbers lies just beyond the range of currently known elements, which means we could potentially discover some new elements that are relatively stable and extremely massive. There are believed to be certain numbers/ratios that are inherently more stable. Hence, larger atoms become more unstable. The ratio of neutrons to protons gradually increases to try to compensate, but this results in the neutrons getting more unstable themselves, resulting in more opportunity for weak forces to destabilize them. Unit 2 Objectives By the end of this unit, you will be able to: Define: proton, neutron, electron, mass number, atomic number, isotope, ion, cation, anion, and orbital. With all of that to consider, as you get larger and larger nuclei with more protons, the electromagnetic forces increase, as well as the distances in the nuclei, putting more strain on the nuclear forces holding it all together. Neutrons will help add to this nuclear force, but they tend to become unstable when they get into too great of concentration and the weak force will cause them to decay into protons.

Fusion allows these protons to get close enough together for the stronger, yet short ranged, nuclear force to overpower the electromagnetic force. The electromagnetic force of the protons wants to push them away from each other. There are several forces at work inside the nuclei of atoms.
