How are different elements produced?
Different elements are produced through various processes in stars and cosmic events. In stars, nuclear fusion occurs, where lighter elements like hydrogen fuse to form heavier elements such as helium, carbon, and oxygen. When massive stars exhaust their fuel, they explode in supernovae, creating and dispersing even heavier elements like gold and uranium through explosive nucleosynthesis. Additionally, elements can form during the Big Bang nucleosynthesis, where the universe's first elements, mainly hydrogen and helium, were created.
