Supernova nucleosynthesis. Supernova nucleosynthesis is a theory of the production of many different chemical elements in supernova explosions, first advanced by Fred Hoyle in 1954. The nucleosynthesis, or fusion of lighter elements into heavier ones, occurs during explosive oxygen burning and silicon burning processes. Those fusion reactions create the elements silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements: vanadium, chromium, manganese, iron, cobalt, and nickel.
At the basic level, the nucleus of an atom is made up of protons and neutrons. At the more fundamental level, the nucleus of an atom is made up of quarks and other sub-subatomic particles, such as leptons and gauge bosons. Two down quarks and one up quark make up a neutron, while one down quark and two up quarks make up a proton.
