Hydrogen undergoes nuclear fusion reaction to form helium in the core of the stars. For this generally a very high temperature ~107 K is required.
The different gases such as helium and hydrogen.
Hydrogen combines with oxygen with explosive force in the presence of a spark. Helium is an inert gas that will not burn or explode, so is much safer to use in balloons and air ships instead of hydrogen.The Hindenburg incident is a good example of why not to use hydrogen in a balloon. In the related links box below I posted an article on it.Helium is more chemically stable than hydrogen and will not burn.study island cheaters.Hydrogen burns very easily and helium doesn't. Because hydrogen is extremely flammable or explosive, it is extremely dangerous to use it in this application. That's why we see helium, and inert gas, used in these lighter than air craft.Because hydrogen is flamable and helium isnt. The airships need a fuel that isnt flamable because if there is a fire, the fuel with explode and cause a huge explosion that will put many peoples safety at risk. Therefore, the clearly safer option is heliumHydrogen is highly combustible and is more reactive compared to helium, as helium is an inert gas.I prefer hydrogen, it is cheaper and reactive. However Helium is often used because it is inert and doesn't burn.
Helium is safer than hydrogen in hot air balloons because it is non-flammable. Hydrogen can ignite easily, posing a greater risk of fire. Additionally, helium is more stable and its lifting capacity is sufficient for use in hot air balloons.
The simplest and easiest reaction to do is deuterium tritium fusion, this makes helium-4 and a free neutron.The next simplest is deuterium deuterium fusion, this can make any of 3 products: helium-4, helium-3 and a free neutron, or tritium and hydrogen.The hardest is multistep, hydrogen hydrogen fusion, this makes helium-2 which instantly beta decays to deuterium, followed by deuterium deuterium or deuterium tritium fusion.There are various other pathways too.
Oxygen can be toxic in hydro concentrations, but it is essential in lower concentrations. Neither helium nor hydrogen are toxic, but they can displace oxygen simply because they take up space and so can cause asphyxiation. Hydrogen is dangerous because it is highly flammable.
In a star's nuclear reactions, hydrogen is converted into helium. This process, known as nuclear fusion, occurs in the core of a star, where high temperatures and pressures cause hydrogen atoms to combine to form helium.
hydrogen atoms in its core, where immense pressure and temperature cause hydrogen nuclei to fuse into helium. This fusion process releases a tremendous amount of energy in the form of light and heat, which powers the Sun and sustains life on Earth.
Over the next few billion years, the hydrogen content in the sun will decrease as it fuses into helium through nuclear fusion. This process will cause the relative amount of helium to increase in the sun over time.

If you are asking "how helium formed the sun?" then for your information, sun and all the stars are formed mostly from Hydrogen. And if you are asking "How helium is formed in the sun?", the answer is that the Hydrogen in the sun fuses in itself(that's where from the sun get's its energy and luminosity) producing variety of elements like helium, carbon oxygen,iron etc.
Over the next billion years, the amount of helium in the Sun will increase as hydrogen is fused into helium in the core through nuclear fusion. This process will cause the Sun to gradually expand into a red giant, using up its hydrogen fuel. After that, it may start fusing helium into heavier elements, while shedding its outer layers into space.
Hot air balloons use hot air. They have a burner to heat the air. Hydrogen balloons were too dangerous because hydrogen is highly flammable, even static electricity could cause an explosion. Helium is safer because helium is not flammable.
Actually, the sun is mostly composed of hydrogen (about 74%) and helium (about 24%). Carbon and oxygen make up only a very small fraction of the sun's composition. The high temperatures and pressures in the sun's core cause hydrogen atoms to fuse together, creating helium and releasing energy in the form of light and heat.
Hydrogen is a colorless gas used in industrial processes, Helium is used in applications such as cooling superconducting magnets, and Carbon dioxide is a greenhouse gas that is released into the atmosphere through human activities like burning fossil fuels.

Hydrogen ions (H+) cause a low pH. When hydrogen ions are present in a solution, the pH decreases, making the solution more acidic.
