Nucleosynthesis (noun, “noo-kuh-lee-oh-sin-this-is”)
Nucleosynthesis is the process by which new nuclei are formed, creating all the elements in our universe.
Composition refers to creating something, so nucleosynthesis involves the creation of nuclei, specifically within atoms. This determines the element of the atom, as different elements are formed by creating new nuclei.
Nucleosynthesis can occur in two ways: by binding protons and neutrons to the nucleus, or by fusing light nuclei into heavier ones.
Most nucleosynthesis occurs in the universe, starting with the Big Bang that created our universe. Lighter elements like hydrogen and helium are believed to have originated from nucleosynthesis in the Big Bang.
Stars also contribute to nucleosynthesis by fusing lighter nuclei into heavier ones, creating elements like carbon and iron in their cores. Even after their deaths, stars can form new elements through supernova explosions, releasing energy to fuse nuclei and create elements like oxygen and heavier elements such as gold and uranium.
