Oxygen is formed in stars by fusion of Hydrogen with Nitrogen. There are various ways this is done, involving various isotopes.
There are links Wikipedia, below. The first deals with the Carbon-Nitrogen-Oxygen cycles, and is specific to this question. The second is more general.
Oxygen is thought to have formed in the core of massive stars through nuclear fusion processes, particularly during supernova explosions. However, oxygen can also be produced through various nucleosynthesis processes in different stellar environments.
Oxygen formed on earth by compound of nuclear fission of sun with helium and hydrogen.
Hydrogen and helium are primarily formed inside stars through nuclear fusion processes. As stars age and go through various stages of stellar evolution, they can also produce heavier elements such as carbon, oxygen, and iron through fusion reactions in their cores.
Heavier elements are formed through nuclear fusion processes that take place in the core of a star. Hydrogen atoms undergo fusion to form helium, and then this process continues to create heavier elements by fusing helium atoms together. As the star fuses lighter elements, it produces heavier elements through a series of nuclear reactions.
Nitrogen, oxygen, and argon are formed through various processes in the universe. Nitrogen mostly originates from the fusion of carbon and helium in stars, while oxygen is primarily formed during the later stages of stellar evolution through nucleosynthesis processes. Argon is mainly produced through the radioactive decay of potassium-40 in rocks on Earth.
Gaseous planets
from nuclear fusion on the surface of the sun when it went nova, but it was also formed by plant life through the calvin cycle
First beryllium is formed, followed by carbon
No, nuclear fusion does not convert oxygen to hydrogen. Fusion involves the joining (fusion) of lighter atoms, such as hydrogen isotopes like deuterium and tritium, to form heavier elements like helium. This process releases large amounts of energy.
Carbon, oxygen, and iron nuclei are commonly found in stars because they are formed through nuclear fusion processes in the cores of stars. Carbon and oxygen are produced through fusion reactions in stars of medium mass, while iron is formed in the later stages of a star's life through various fusion processes. These elements are essential building blocks for heavier elements and are crucial for the evolution of stars.
In the most common stellar fusion, helium gas is formed from the fusion of hydrogen nuclei.
Solar energy is formed by nuclear fusion in the sun
No elements were formed in the big bang. After quite some time, hydrogen began to form, and it is the main constituent of stars. The main by-product of nuclear fusion in stars is helium.
Most stars that are around today are made of old material from dead stars. Those old stars produced oxygen as a product once they started fusing helium and heavier elements. Some old stars are currently producing oxygen through nuclear fusion.
Iron is the most massive element that can be formed by nuclear fusion with the liberation of energy. This is because fusion reactions beyond iron require an input of energy rather than liberating energy.
Heavier elements are formed through nuclear fusion reactions in the core of a star. Hydrogen atoms are fused together under high pressure and temperature to form helium. Further fusion reactions involving helium nuclei lead to the formation of heavier elements like carbon, oxygen, and up to iron. These elements are produced through a series of nuclear reactions that occur as the star evolves.
Oxygen is thought to have formed in the core of massive stars through nuclear fusion processes, particularly during supernova explosions. However, oxygen can also be produced through various nucleosynthesis processes in different stellar environments.
