Kinds of nucleosynthesis :

• primordial nucleosynthesis (6 facts) (big-bang nucleosynthesis) - The production of heavy nuclei from the fusion of lighter ones during the Big Bang. The infant universe consisted of only hydrogen, the lightest of all atomic nuclei, because any heavier nuclei would have come apart in the intense heat. All other elements would have to be formed later, in nucleosynthesis processes. It is believed that most of the helium, the next lightest element after hydrogen, was formed when the universe was a few minutes old, The creation of elements that occurred just minutes after the Big Bang. According to standard theory, primordial nucleosynthesis gave the universe only five nuclei, all lightweight: hydrogen-1, hydrogen-2 (or deuterium), helium-3, helium-4, and lithium-7., Production of atomic nuclei occurring during the first three minutes after the big bang., The process, which took place between one second and 3-4 minutes after the beginning, in which the protons and neutrons of the primordial soup condensed to form the lightest atomic nuclei: Deuterium, Helium-3, Helium-4, and Lithium-7. See isotope and Lithium.
• stellar nucleosynthesis (1 kind, 5 facts) - The production of heavy nuclei from the fusion of lighter ones within a star. The Sun presently converts hydrogen into helium.
• X-process (2 facts) - The unknown nucleosynthetic process that Burbidge, Burbidge, Fowler, and Hoyle said had formed the light nuclei deuterium, lithium, beryllium, and boron.
