How does hydrogen turn to helium
WebSep 11, 2014 · Helium 4 makes up over 99% of naturally occurring helium. Hence, when we speak of "helium", without specifying which isotope, we're usually speaking of helium 4. Helium 4's nucleus consists of two protons … WebOver large amounts of time, hydrogen fuel gets burned through a series of reactions, producing, in the end, large amounts of helium-4. This fusion reaction, where heavier elements are created...

Did you know?
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 ...

WebJul 7, 2024 · What is the process of converting hydrogen to helium? In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four … WebAt 200,000,000 degrees Celsius, the helium atoms fuse to form carbon atoms in the core. The last of the hydrogen gas in the outer shell is blown away to form a ring around the core. This ring is called a planetary nebula. When the last of the helium atoms in the core are fused into carbon atoms, the medium size star begins to die.
http://burro.astr.cwru.edu/Academics/Astr221/StarPhys/nuclear.html WebHydrogen was once used to fill balloons but it is dangerously reactive. Because it is very unreactive, helium is used to provide an inert protective atmosphere for making fibre optics and semiconductors, and for arc welding.
