Why are lighter elements used in fusion reactions?

Because their binding energy is greater than that of their products, thus permitting an energy release. This is the same reason heavier elements are used in fission reactions. The range of elements from iron to lead has the lowest binding energy.


All of the elements heavier than oxygen are created by fusion reactions in?

stars through processes such as supernova explosions. These reactions involve the fusion of lighter elements to create heavier ones, including elements like gold, uranium, and plutonium.


How are the elements carbon nitrogen and oxygen produced in stars like the sun?

These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.


What kind of reaction does oxygen undergo fusion or fission?

Oxygen undergoes fusion reactions in the cores of massive stars, where it can fuse into heavier elements. Oxygen does not undergo fission reactions naturally.


Nuclear fusion only releases energy when elements that are lighter than what element are involved?

Nuclear fusion only releases energy when elements lighter than iron are involved. This is because elements lighter than iron release energy due to the process of fusion, while elements heavier than iron require energy to be input for fusion to occur.


Why can elements be produced in the sun but not in the earth atmosphere?

Over time, the fusion reactions can form as the reactions that form nuclei of slightly heavier elements, such as carbon, nitrogen, and oxygen. Thank you = )

What produces all the known elements in universe other than hydrogen?

fusion reactions in stars


Which elements are involved during the process of fusion in the sun?

Hydrogen is turned into helium in the fusion process that releases the Sun's energy.


Explain how heavier elements are formed from hydrogen within the core of a star?

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.


Why are all elements heavier then iron created during a supernova?

The rapid collapse of the star compresses atoms together and may cause nuclear fusion and make heavier elements.
