In the sun and other stars it occurs by protons reacting together to produce helium nuclei. See link below. On Earth experimenters are trying to fuse nuclei of deuterium and tritium as the best combination for success, but only very short (less than 1 second) bursts have so far been achieved.
What else can I help you with?
Which do you currently use nuclear fusion or fission?
I currently use nuclear fusion.
Does fusion reaction occur in an atomic bomb?
Yes, fusion reactions occur in a hydrogen bomb, which is a type of nuclear bomb. The high temperatures and pressures generated by the fission reaction in the bomb can trigger fusion reactions between hydrogen isotopes. This fusion reaction releases a large amount of energy, contributing to the destructive power of the bomb.
Is energy released during fission but absorbed during fusion?
Energy is released during fusion and fission.
How is the production of electricity by fission better than nuclear fusion?
In principle fusion should be better for the environment because it does not produce the active fission products. The snag is that it has not been made to work yet, and won't be for many years to come, so as a practical way of producing electricity it does not come into play, and we have to say fission is better than a non-existent fusion
Fission and fusion are examples of what?
Nuclear processes that can release large amounts of energy.
Does fission or fusion occur in the sun?
Fusion occurs in the sun.
Does fusion or fission occur in the sun?
Fusion occurs in the sun.
What is sun fission?
Fission does not occur in the sun, it is fusion which produces the sun's energy
When does fission occur in a star?
Never, only fusion
Can fission occur after fusion?
No, fission and fusion are two distinct nuclear reactions. Fusion involves the joining of atomic nuclei to release energy, while fission involves the splitting of atomic nuclei. They are not directly connected processes, so fusion does not lead to fission.
Can fision occur in a star?
Not typically. When a star burns it starts with fusion of Hydrogen. Later heavier atoms are formed, also by fusion. It is believed that the very heavy atoms, that release energy when split (fission) are only formed by very massive stars . These atoms are also formed by fusion. When one of these very massive stars explodes (super nova) it spews out its atoms and during this process its possible some fission will occur, but for the most part star evolution is a fusion story.
Detonation of a fusion type hydrogen bomb is started by?
Detonation of a fusion hydrogen bomb is initiated by the primary fission bomb, which generates high temperatures and pressures needed to trigger fusion reactions in the hydrogen isotopes. The fission bomb compresses and heats the fusion fuel to the point where nuclear fusion reactions can occur, releasing vastly more energy than the fission reaction alone.
Which do you currently use nuclear fusion or fission?
I currently use nuclear fusion.
Does fusion reaction occur in an atomic bomb?
Yes, fusion reactions occur in a hydrogen bomb, which is a type of nuclear bomb. The high temperatures and pressures generated by the fission reaction in the bomb can trigger fusion reactions between hydrogen isotopes. This fusion reaction releases a large amount of energy, contributing to the destructive power of the bomb.
Is reaction on sun a fusion or fission?
fission..sup
Is atomic bomb fission or fusion?
Fission.
Why are high temperatures needed for fusion reactions to occur but not fission reactions to occur?
In fusion reactions, nuclei need to overcome the strong electromagnetic repulsion to merge and release energy, requiring high temperatures to achieve the necessary kinetic energy. In fission reactions, nuclei need to be bombarded by neutrons to induce a split, a process that can occur at lower temperatures.
