How does hydrogen turn to helium
WebAs a side effect of the process, some carbon nuclei fuse with additional helium to produce a stable isotope of oxygen and energy: 12 6 C + 4 2 He → 16 8 O + γ (+7.162 MeV) Nuclear fusion reactions of helium with hydrogen produces lithium-5, which also is highly unstable, and decays back into smaller nuclei with a half-life of 3.7 × 10−22 s . WebApr 14, 2024 · The first stars converted hydrogen to helium via nuclear fusion and then converted helium to heavier elements, and when they exhausted this nuclear fuel, they could no longer support themselves ...

WebJun 3, 2024 · By the end of Big Bang nucleosynthesis, on average 12 out of 13 atoms will be hydrogen (92%) and the remaining atom will be helium (8%); or by mass, with a helium … WebHydrogen is converted into helium by a succession of nuclear reactions that change four protons into a helium nucleus, two positrons, and two neutrinos. (A positron is a particle like an electron but with a positive charge; a neutrino is a particle with no charge and negligible mass.) Two different reaction chains exist.
WebDec 2, 2010 · But helium is the second most common element after hydrogen. Together they make up more than 98 percent of the matter in the universe. (Luminous matter, that is; dark matter is a whole other story.) WebHydrogen is generally less expensive than helium. Helium supply is getting low. (There is a helium shortage) Hydrogen is easier to find than helium in some parts of the world. These may not be good enough reasons to justify the dangers, but balloons are still filled with hydrogen in some areas.
WebShort answer: It's a reaction that actually has multiple steps, but the gist is that the protons turn into neutrons, and emit a positron (anti-electron) and a neutrino in the process. Long answer: The overwhelming majority of matter in the universe is hydrogen-1 which is basically lone protons. This hydrogen gas, in big clouds, condenses to ...
