To get an overview over this process, search for "proton-proton chain reaction" in Wikipedia or other online resources.
In the proton-proton nuclear reaction, either three or five steps occur. Initially, we see the fusion of two hydrogen-1 nuclei to form a hydrogen-2 nucleus. We also need another of these reactions to create another hydrogen-2 nucleus. That's either one or two steps, depending on your point of view. Now we see a hydrogen-2 nucleus fuse with a hydrogen-1 nucleus to create a helium-3 nucleus. And we need two of those helium-3 nuclei, so that's a total of one or two more steps, and yet again it depends on your point of view. Lastly, we see the two helium-3 nuclei fuse to form a helium-4 nucleus (with the release of two hydrogen-1 nuclei). That's a total of three steps or five steps, depending on how you want to look at the first fusion reactions to create hydrogen-2 and helium-3.

What comes after nuclear fusion?
After nuclear fusion, the next steps for a star depend on its mass. For lower-mass stars like our Sun, the core contracts and heats up, triggering helium fusion. For higher-mass stars, a series of fusion reactions occur with progressively heavier elements until iron is produced in the core. Once iron is produced, the star may undergo a supernova explosion or collapse to form a neutron star or black hole.
What nuclear reaction responsible for release of energy by the sun?
It's nuclear fusion. There are several steps, but the overall reaction converts hydrogen into helium, with the release of energy.
How does sun provides energy?
The Sun produces energy by nuclear fusion. It follows the steps of the proton-proton(P-P) chain, which converts hydrogen to helium. The core of the Sun produces about 99% of heat through fusion.

In nuclear fusion high pressure and temperature fuse two deuterium nuclei and transform them into?
In nuclear fusion, high pressure and temperature enable two deuterium nuclei to fuse, resulting in the formation of a helium-3 nucleus and a neutron. This process releases a significant amount of energy, which is a key principle behind the energy produced in stars, including our sun. The fusion of deuterium is one of the steps in the broader fusion processes that ultimately produce heavier elements and substantial energy output.
How are stars formed, step by step, from the initial collapse of a cloud of gas and dust to the ignition of nuclear fusion in their cores?
Stars are formed through a series of steps starting with the gravitational collapse of a cloud of gas and dust. As the cloud collapses, it heats up and forms a protostar. The protostar continues to contract and heat up until the core reaches temperatures high enough for nuclear fusion to begin. Once nuclear fusion ignites in the core, the star is born and begins to shine brightly.
What is the product of nuclear fusion in the sun?
In the core of the Sun (and other stars) protons (hydrogen nuclei) combine to produce Helium nuclei (alpha particles). In the process, positrons, neutrinos and gamma rays are produced. There are several nuclear reactions that form the steps that go from protons to helium nuclei and the steps impart significant kinetic energy to the products of the reactions. The products of hydrogen fusion are helium, neutrinos, electromagnetic radiation and heat energy.
Who discovered nuclear fusion in 1944?
Nuclear fusion occurs naturally in stars. Artificial fusion in human enterprises has also been achieved, although it has not yet been completely controlled as an energy source; successful nuclear physics experiments have been performed involving the fusion of many different nuclear species, but the energy output is negligible in these studies. Building upon the nuclear transmutation experiments of Ernest Rutherford done a few years earlier, fusion of light nuclei (hydrogen isotopes) was first observed by Mark Oliphant in 1932; the steps of the main cycle of nuclear fusion in stars were subsequently worked out by Hans Bethe throughout the remainder of that decade.

How sun provides energy?
The Sun produces energy by nuclear fusion. It follows the steps of the proton-proton(P-P) chain, which converts hydrogen to helium. The core of the Sun produces about 99% of heat through fusion.
What is the procedure of nuclear fallout shelter exercise?
A nuclear fallout shelter exercise typically involves practicing the steps for seeking shelter in case of a nuclear attack or nuclear fallout. This may include identifying a suitable shelter location, stocking it with essential supplies, practicing how to quickly get to the shelter, and understanding how to stay safe and secure inside the shelter for an extended period. It is important to follow guidelines provided by emergency management authorities and practice these steps regularly to be prepared.
