I may be incorrect but I believe it's fission

Small stars are powered by the fusion of deuterium and tritium, to isotopes of hydrogen. Each reaction forms a helium nucleus, which is slightly less massive than the mass of the reactants, so the excess energy is release in light and heat. Larger stars may fuse helium into heavier elements, but no heavier than iron, because iron is the most stable element and its fusion will result in a loss of energy. When the core of iron gets too massive, the star explodes and outshines the whole galaxy. This is where all the heavier elements are created.Fission refers to the splitting or large atomic nuclei into two smaller ones by the impact of a neutron or an alpha particle (helium nucleus). The split releases more neutrons to hit another two nuclei resulting in a self sustaining reaction. Humans have been able to make runaway fusion reactions in hydrogen bombs, but controlled reactions have still not been achieved. We have been able to make controlled fusion reactions, which are used in nuclear reactors.

You prolly copy pasted that. And the noble gases are the most stable elements.

No. It is from my accumulated knowledge over 11 years. Also, iron is the most stable element. Noble gasses have the most stable electronic structure, but the iron nucleus is hardest to fuse or fission. Radon, the last non-synthetic noble gas, is actually radioactive and ununoctium has a very short halflife, measured in seconds.
