In this process, hydrogen-1 is converted into helium-4. Energy is freed up in the process.
a chain reaction
These are not chemical reactions but thermonuclear reactions.
The only place in the universe where nuclear fusion can occur on its own is in the interior of stars. After closely observing nature, and adapting its laws to fulfill human requirements, our advanced civilization has succeeded in creating nuclear fusion at will, on a small scale. Unfortunately, the only useful application successfully developed so far with our superior intellect is the construction of nuclear bombs and weapons.
fusion
Nuclear fusion is the process that powers stars, such as our sun.
There is no fire in the sun, that is a chemical process. The process in the core is thermonuclear fusion.

No, a solar prominence is not a thermonuclear reaction. Solar prominences are large, bright features extending outward from the Sun's surface due to magnetic activity. Thermonuclear reactions, on the other hand, occur in the Sun's core where hydrogen atoms are fused into helium, releasing energy in the process.
The high temperature in the centers of stars is necessary for fusion to occur because it provides the particles with enough energy to overcome their natural repulsion and come together to fuse. At such high temperatures, the particles have sufficient kinetic energy to collide and fuse, releasing enormous amounts of energy in the process.
a hydrogen bomb is a fusion bomb. even though in standard types of hydrogen bombs 90% of the yield is fission, caused by uranium-238 fission by 15 MeV neutrons from the fusion reaction.

The thermonuclear reactions in the Sun occur in its core, where hydrogen nuclei fuse to form helium nuclei. This process releases energy in the form of light and heat, which powers the Sun and sustains life on Earth. The most common reaction is the proton-proton chain reaction, where hydrogen nuclei collide to form helium-4 nuclei.
There are several processes that happen in atomic bombs, the main ones are:Fission bombs - hydrodynamics, neutron chain reaction, fission.Fusion bombs - hydrodynamics, radiation transport, thermonuclear fusion, fission.Many other secondary processes occur also.

Man has attempted to use fusion as a source of energy on Earth in large experimental reactors such as the Joint European Torus (JET) in the UK and the International Thermonuclear Experimental Reactor (ITER) in France. These projects aim to replicate the fusion reactions that occur in the sun to generate clean, abundant energy.
