Heavier elements in the universe are primarily formed through nuclear fusion processes within the cores of stars. Elements beyond iron are typically formed in supernova explosions, where the extreme conditions allow for the synthesis of elements such as gold, silver, and uranium.
The heavier elements in the universe were primarily formed through processes such as stellar nucleosynthesis and supernova explosions. In stars, nuclear fusion combines lighter elements like hydrogen and helium into heavier elements up to iron. Elements heavier than iron are typically formed during supernovae, where the intense energy and neutron capture processes create these elements. Additionally, some heavy elements may also form through the merging of neutron stars.
Elements heavier than iron are formed through processes like supernova explosions, where the intense heat and pressure create conditions for nuclear fusion to occur, leading to the synthesis of heavier elements. This process is known as nucleosynthesis and is crucial for the creation of elements like gold, uranium, and beyond in the universe.
Chemical elements are formed in the Universe by stellar nucleosynthesis.
Elements heavier than iron are formed in super-nova explosions.
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.

Once the Universe got cold enough, atoms could form. It is believed that in the Big Bang, only hydrogen, helium, and small amounts of lithium formed; all heavier elements were formed later, through fusion in stars.Once the Universe got cold enough, atoms could form.

Hydrogen and helium were formed shortly after the creation of the universe (when the protons and alpha particles combined with electrons). Everything else was formed within the core of stars (by fusion reactions).
Elements heavier than hydrogen and helium primarily formed in the cores of stars through nuclear fusion processes. Elements up to iron are formed in the cores of stars, while elements heavier than iron are typically produced in supernova explosions or neutron star mergers. These heavy elements are dispersed into space during these catastrophic events, enriching the interstellar medium from which new stars and planets can form.
