They are fused into helium and create energy. But it takes 4 hydrogen atoms to make 1 atom of helium. The Hydrogen is first converted to Deuterium (heavy hydrogen), and the two deuterium atoms fuse to make the Helium atom. This process releases a lot of energy, not the least because of the neutrons released. Lol
What else can I help you with?
What happens when temperatures and pressures are so high in the very center of the sun?
In the very core of the sun, temperatures and pressures are so high that nuclear fusion occurs, where hydrogen atoms fuse to form helium, releasing immense amounts of energy in the process. This energy is what provides the heat and light that are emitted from the sun.
In what forms does Hydrogen exist?
Under ordinary conditions ... those in which humans could reasonably expect to live ... hydrogen is a diatomic gas.At very high temperatures it becomes an ionized plasma.At very low temperatures it becomes a liquid and finally a solid.It's hypothesized that at very high pressures hydrogen may become metallic, though it would require pressures far greater than we have been able to create on Earth so far.In nature it exists as part of a compound; it is too reactive to stand alone. If you care to separate it out you can cause it to be a solid, liquid, gas, or plasma.
Why is argon used as a shielding gas in some types of high temperature welding?
Argon is an inert gas, hydrogen is not. Hydrogen is flammable and would negatively impact the arc process.
What is the only thing in nature that can be a solid liquid or gas?
Water is a very common example. Many other substances like Mercury, organic compounds, bromine can do this same thing at easily attainable temperatures and pressures. Some like iron and nickel need very high temperatures to attain the gaseous state and some like hydrogen and helium need to reach almost absolute zero to become solids.
What climate has very low rainfall and high temperatures throughout the year?
desert
What happens to hydrogen atoms at a very high temperatures?
They ionize (into plasma).
What happens when temperatures and pressures are so high in the very center of the sun?
In the very core of the sun, temperatures and pressures are so high that nuclear fusion occurs, where hydrogen atoms fuse to form helium, releasing immense amounts of energy in the process. This energy is what provides the heat and light that are emitted from the sun.
How are elements H an He made?
Hydrogen was formed the first by nucleosynthesis from protons; helium is obtained from hydrogen by fusion at very high temperatures.
Is hydrogen nonmetal or metal?
Hydrogen is a non-metalic gas. It is sometimes described as a metaloid.At very very low temperatures and very very high pressures hydrogen has all the properties of a metal, so is commonly considered to be a metal in these very unusual conditions.
Is hydrogen like plasma?
Yes, plasma is the fourth state of matter where the gas phase is heated to high temperatures, causing the atoms to ionize. Hydrogen can be in a plasma state at very high temperatures, such as in stars or during fusion reactions.
The sun and the fuel it contains?
The fuel is not a regular chemical fuel, but hydrogen, which gets converted to helium through nuclear fusion, at very high temperatures.The fuel is not a regular chemical fuel, but hydrogen, which gets converted to helium through nuclear fusion, at very high temperatures.The fuel is not a regular chemical fuel, but hydrogen, which gets converted to helium through nuclear fusion, at very high temperatures.The fuel is not a regular chemical fuel, but hydrogen, which gets converted to helium through nuclear fusion, at very high temperatures.
What happens to hydrogen atoms at a very high temptatute?
At very high temperatures, hydrogen atoms can undergo nuclear fusion to form helium. This process releases a large amount of energy and is the same process that powers stars. In extreme conditions, hydrogen atoms can also become ionized, meaning they lose their electrons.
What fuses hydrogen to form helium?
Nuclear fusion is the process that fuses hydrogen atoms together to form helium. This process occurs in the core of stars, including our sun, where high temperatures and pressures allow hydrogen nuclei to overcome their electrostatic repulsion and combine to form helium nuclei.
What Elements are involved in the Sun's thermonuclear processes?
Within our Sun, hydrogen is fused into helium at very high temperatures. This is how the Sun is powered.
What is the chemistry background of nuclear fusion?
Nuclear fusion is based on the helium nucleus synthesis from two hydrogen atoms at very high temperatures.
Is hydrogen an solid?
At room temperature, no. However in laboratories where they can decrease the temperature to very low temperatures it can be. Infact its melting point is -259 degrees Celsius
Can hydrogen be heated?
Yes, hydrogen can be heated like other substances. When heated, hydrogen can change states from a gas to a plasma at very high temperatures. Heating hydrogen can also make it react with other elements or compounds in different chemical reactions.
