Because in the sun, nuclear fusion (or thermonuclear reaction) is happening, means an atom core is joined with other's atom core, making it a bigger atom and more unstable. In the sun and other stars, one hydrogen atom is joined itself with the other hydrogen atom and reacting, releasing particles, positron, neutrino and energy. The result is 2H. Then it joined itself with another 1H atom. Then the fusion reaction happens. It's repeating until the third reaction, where 3He is joining with other 3He, releasing two 1H and a 4He. In short, one Hydrogen atom join another one Hydrogen Atom and result two hydrogen atoms, Neutrino, and Positron (1H + 1H = 2H, Positron, Neutrino). This process is repeating twice (although the second time, 2H is joining 1H = 2H + 1H = 3He). Then, the Third time, where the Hydrogen atoms become Helium atoms, they join together and releasing two 1 H and 4He atoms (3He + 3He = 2x 1H, 4He). ( The fusion also the one who detonate the Hydrogen Bomb).

∙ 11y agoEnergy is released when hydrogen nuclei fuse to form helium nuclei.
There is more than one way this can happen. The basic overall reaction
is that four hydrogen nuclei make a helium nucleus.
A hydrogen nucleus is a single proton. A helium nucleus is 2 protons and 2 neutrons.
If you want properly "balanced " equations its best to write down all the steps involved, but that's not needed here.
The "binding energy per nucleon" of a helium nucleus is more than that of a hydrogen nucleus. Refer to the curve for "binding energy per nucleon" against "mass number" (link given below).
Since the binding energy per nucleon for helium is greater than hydrogen, the nucleons (protons and neutrons) in helium are more tightly bound than in hydrogen. The helium nuclei thus formed will be more stable than the hydrogen nuclei. Energy will be released as energy is conserved during the reactions.
Another way to look at this is: the mass of the helium nucleus is less than the mass of 4 hydrogen nuclei. So, energy is released according to Einstein's famous equation E = mc2.

Four hydrogen atoms have a certain mass; when they merge to form one helium atom, the mass of the helium atom is a tiny bit less. A tiny bit of mass is turned into a great deal of energy.

The nuclei of hydrogen has a positive charge How does this affect the chances of nuclear fusion occurring?
The positive charges of hydrogen nuclei cause repulsion, it is very difficult to bring two hydrogen nuclei close enough for them to fuse into helium. However, if they can be forced to fuse, a huge amount of energy is released.
What element do you get if you fuse two helium nuclei together?
Nuclear fusion occurs when two nuclei fuse together. This is frequently nuclei of deuterium and tritium (both hydrogen isotopes), which form a helium nucleus plus a neutron.
When 2 hydrogen nuclei fuse do they make helium?
No, an element depends on the average amount of electrons it has. Actually in stellar nuclear fusion it takes 4 hydrogen nuclei to fuse to make one helium nucleus, the process is called proton-proton burning.
What nuclear process coverts helium and hydrogen gases from lighter to heavier elements?
The process is called fusion; hydrogen nuclei are fused together to make helium. At much higher temperatures and pressures, the helium can fuse into carbon and nitrogen and oxygen.
What element does a star run out of that causes them to die?
Hydrogen and helium; those two elements are the fuel for the stars. First they fuse hydrogen to helium, later they fuse helium to heavier elements.
What element is formed when hydrogen nuclei fuse together?
Helium
What accurately describes the main reaction that generates the Sun's light?
hydrogen nuclei fuse forming helium and releasing energy

When different isotopes of hydrogen fuse in the sun nuclei of what are produced?
Helium is produced
What is the simplest form of fusion that occurs in stars?
Hydrogen nuclei (protons) fuse together and produce helium nuclei
When is energy in the sun produced?
..particles (nuclei) fuse together to form heavier nuclei. Initially, two protons fuse together (hydrogen atom nuclei) to form deuterium. These in turn may fuse with further protons, or with another deuterium nuclei to for a helium nuclei. As the heavier nuclei form, lots of energy is released.

What are elements the sun uses to produce energy?
Its mainly going to be Hydrogen nuclii. At the suns core, two protons fuse together (hydrogen atom nuclei) to form deuterium. These in turn may fuse with further protons, or with another deuterium nuclei to for a helium nuclei. As the heavier nuclei form, energy is released. Later on in the Stars life, fusion of the helium nuclii may take place a lot more often, as the preferred fuel of Hydrogen is depleted.
What keeps atoms from fusing together?
It is the nulei which fuse. Nuclei are positively charged and thus repel each other. The kinetic energy of the nuclei must be very large for nuclei to be able to fuse, such as at the surface of the sun, where hydrogen nuclei fuse to form helium nuclei.
Describe the reaction that produces the suns energy?
It is a fusion reaction in which the nuclei of hydrogen atoms fuse and form helium.
What nuclei fuse to form oxygen?
Oxygen is produced through repeated hydrogen fusion in stars. One such process would start with the hydrogen atoms fusing to form helium. And then the helium would fuse to form beryllium. That in turn would fuse to create oxygen.
