They are usually first formed in supernova explosions. These would be dispersed in space and might end up in a planetary system..The heavier, radioactive, nuclei would then form their daughter elements.
In cool stars, elements such as hydrogen and helium are primarily produced through nuclear fusion in their cores. Elements heavier than helium (e.g., carbon, oxygen, and iron) are formed through nucleosynthesis processes during the later stages of a star's lifecycle, such as in red giant stars or during supernova events.
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.
Most natural elements are formed in stars through nuclear fusion processes. In the cores of stars, hydrogen atoms fuse to create helium and, in larger stars, heavier elements up to iron are produced. Elements heavier than iron are typically formed during supernova explosions, where the intense energy allows for the fusion of heavier nuclei. Additionally, some lighter elements are formed in processes like cosmic ray spallation and during the Big Bang nucleosynthesis.
All elements up to iron (atomic number 26) were primarily formed in the interiors of stars through the process of nuclear fusion. During stellar nucleosynthesis, lighter elements such as hydrogen and helium fuse together under immense pressure and temperature to create heavier elements up to iron. Elements heavier than iron are generally formed during explosive events like supernovae, where the extreme conditions allow for rapid neutron capture processes. Thus, while iron is formed in stellar cores, elements beyond iron require more violent cosmic events for their synthesis.
Not all elements are formed in stars. While many lighter elements, such as hydrogen and helium, were created during the Big Bang, heavier elements like carbon, oxygen, and iron are synthesized within stars through nuclear fusion. Additionally, elements heavier than iron are primarily formed during supernova explosions and through processes like neutron capture. Some elements, like lithium and beryllium, are also thought to be produced in cosmic ray spallation rather than in stellar processes.
Elements heavier than iron are formed in super-nova explosions.
Supernova form heavier elements
Elements heavier than hydrogen are formed through nuclear fusion processes in stars. When lighter elements fuse together in the intense heat and pressure within a star's core, they can form heavier elements. This process continues throughout a star's life until elements up to iron are created. Elements heavier than iron are formed through supernova explosions or in the collisions of neutron stars.
Chemical elements are formed in the Universe by stellar nucleosynthesis.

Elements heavier than helium (e.g., carbon, oxygen, and iron) are formed through nucleosynthesis processes during the later stages of a star's lifecycle, such as in red giant stars or during supernova events.
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.

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.

A few elements past iron can form in the star by neutron capture and beta decay. However the majority can only be formed by the blast shockwave of a supernova, which can form elements significantly beyond Uranium.
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.

Heavier elements like carbon, oxygen, and iron were formed in the cores of stars through nuclear fusion processes. When massive stars exhaust their fuel, they go supernova, releasing heavy elements into space. These elements then become part of new stars and planets, including Earth.
