Web29 de nov. de 2024 · Nitrogen is rare compared to carbon and oxygen. It is a factor 5-10 less common in our galaxy. It is produced in the CNO cycle but also via photodisintegration and beta decays. Most lithium is still from the big bang, the other light nuclides are products from cosmic rays or side-reactions in fusion processes. Nov 28, 2024. WebCNO CYCLE for fusing four protons into a helium nucleus employs ordinary carbon, , as a catalyst, which is regenerated. Neutrinos are released in the second and fifth steps of the cycle. Because they share energy with the …
WebHelium has a very low viscosity, a high diffusion coefficient, and the smallest atom of any element. These characteristics make helium very hard to contain.
