Nuclear binding energy In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy. The difference between the mass of 4 H atoms and 1 He atom is 0.02862 AMU which is only 0.71% of the original mass. This small fraction of the mass is converted into energy. If 4 grams (1/8 ounce) of H are converted to He, only 2.8x10-3 grams of the mass is converted to energy: How much energy is generated from converting such a tiny amount of mass? We can calculate by using Einstein's famous formula. E = mc 2

- Let us assume that cold fusion works like plasma fusion (hot fusion), converting deuterium into helium and releasing energy. Actually, it is probably more complicated than hot fusion, but broadly speaking it releases energy on the same scale, with roughly the same amount of fuel, and it does produce helium.

Helium After hydrogen, Helium is the second lightest element and also the second most abundant element in the universe, (hydrogen being number one), created during big bang nucleosynthesis and to a lesser extent from nuclear fusion of Hydrogen in stars.early all helium on Earth is a result of radioactive decay. The decay product is primarily found in minerals of uranium and thorium, including cleveites, pitchblende, carnotite, monazite and beryl, because they emit alpha particles, which consist of helium nuclei (He 2+) to which electrons readily combine.

Helium - He Gaseous chemical element, symbol: He, atomic number: 2 and atomic weight 4,0026 g/mol. Helium is one of the noble gases of group O in the periodic table. It’s the second lightest element. The main helium source in the world is a series of fields of natural gas in the United States.

Stellar nucleosynthesis In 1920, Arthur Eddington, on the basis of the precise measurements of atomic masses by F.W. Aston and a preliminary suggestion by Jean Perrin, proposed that stars obtained their energy from nuclear fusion of hydrogen to form helium and raised the possibility that the heavier elements are produced in stars.

- Helium (atomic number 2, symbol He) is a non-toxic, tasteless, odorless, and colorless gas. Heading the noble group, it is an inert monoatomic gas, and its melting and boiling points are some of the lowest compared with other elements. Except in extreme conditions, helium exists as gas only.

Sun Fusing hydrogen into helium releases around 0.7% of the fused mass as energy, so the Sun releases energy at the mass-energy conversion rate of 4.26 million metric tons per second.

Nuclear binding energy The sum of the weight (per mole) of the products is 0.0246 g less than the sum of the weights of the reactants. In the Bethe cycle (the series of reactions in the sun by which solar energy is produced), 4 moles of protons weighing 4.03228 g are converted to 1 mole of helium weighing 4.00336 g, a loss of 0.02892 g.

Nuclear Fusion Power Fusion powers the Sun and stars as hydrogen atoms fuse together to form helium, and matter is converted into energy. Hydrogen, heated to very high temperatures changes from a gas to a plasma in which the negatively-charged electrons are separated from the positively-charged atomic nuclei (ions).

Hydrogen By far the most important process for making hydrogen is by steam reforming. The key parts of the process are the conversion of a carbon-containing material to a mixture of carbon monoxide and hydrogen followed by the conversion of carbon monoxide to carbon dioxide.

What is the difference between nuclear fusion and nuclear fission? A huge amount of mass is above you, squeezing down on you from all sides. This is what happens to the hydrogen gas in the core of the Sun. It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is called nuclear fusion.In the process some of the mass of the hydrogen atoms is converted into energy in the form of light.The same process occurs in thermonuclear (fusion) bombs. In the Sun the process occurs in a controled manner. In a bomb it happens all at once in a big chain-reaction explosion.his is called nuclear fusion.

What is Fusion? The fusion reaction that is easiest to accomplish is the reaction between two hydrogen isotopes: deuterium, extracted from water and tritium, produced during the fusion reaction through contact with lithium.When deuterium and tritium nuclei fuse, they form a helium nucleus, a neutron and a lot of energy.he fusion reaction that is easiest to accomplish is the reaction between two hydrogen isotopes: deuterium, extracted from water and tritium, produced during the fusion reaction through contact with lithium.

Stellar nucleosynthesis In 1939, in a paper entitled Energy Production in Stars, Hans Bethe analyzed the different possibilities for reactions by which hydrogen is fused into helium. He defined two processes that he believed to be the sources of energy in stars.

Helium For large-scale use, helium is extracted by fractional distillation from natural gas, which can contain as much as 7% helium. Since helium has a lower boiling point than any other element, low temperature and high pressure are used to liquefy nearly all the other gases (mostly nitrogen and methane).

- Thanks for the clarification but I'm still a tad confused because the book states the following:-. To see how much mass is consumed, we compare the combined mass of four hydrogen atoms (the ingredients) to the mass of one helium atom (the product) 4 hydrogen atoms = 6.692 x 10^-27kg. - 1 Helium atom = 6.645 x 10^-27kg. Mass lost = 0.048 x 10^-27 kg.

- After helium is used up in the core, the core contracts while helium and hydrogen fusion continue in outer shells. The core contracts until carbon ignition occurs, and the star moves left again on the H-R diagram while carbon fusion occurs in the core.

Helium Helium is named for the Greek god of the Sun, Helios. It was first detected as an unknown yellow spectral line signature in sunlight during a solar eclipse in 1868 by French astronomer Jules Janssen.

Stellar evolution Later, as the preponderance of atoms at the core becomes helium, stars like the Sun begin to fuse hydrogen along a spherical shell surrounding the core. This process causes the star to gradually grow in size, passing through the subgiant stage until it reaches the red giant phase.

AST1002 Chapter 13 In the first, the primary production of energy is from hydrogen burning in a shell around the core. In the process of helium shell fusion in a low-mass star near the end of its life, the star moves upward and to the right on the asymptotic giant branch of the Hertzsprung-Russell diagram.

Helium is most commonly a gas, except for in extreme conditions. It has the atomic number 2, melts at -272 degrees Celsius and boils at -269 C. Helium is used in balloons because it is lighter than air and will make whichever container it is in float if the container itself is light enough.
