WebSep 22, 2024 · Where are light and heavy elements formed? The answer is supernovae. In a supernova explosion, neutron capture reactions take place (this is not fusion), leading to the formation of heavy elements. This is the reason why it is said that most of the stuff that we see around us come from stars and supernovae (the heavy elements part). WebThe elements formed in these stages range from oxygen through to iron.
