Nuclear Fusion The main overall nuclear fusion reaction is the fusion of four hydrogen atom nuclei to form a bigger nucleus of a helium atom i.e. 4 1H1 $\rightarrow$ 4He2 + 2 0e+1+ energyi.e., 4 Hydrogen nuclei -----> Helium nucleus + 2 positrons + energy.

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. 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.

How are light and heavy elements formed?  (Advanced) The answer is supernovae. In a supernova explosion, neutron capture reactions take place (this is not fusion), leading to the formation of heavy elements. This is the reason why it is said that most of the stuff that we see around us come from stars and supernovae (the heavy elements part).

- up vote 17 down vote accepted. With normal stars, the burning, that is to say the fusion reaction, produces a pressure that counteracts the pull of gravity to keep the star from collapsing. But with neutron stars, the protons and electrons in the star have combined into neutrons*. The Pauli exclusion principle causes the neutrons to resist further compression. That is, the neutrons, being identical fermions, can't all be put in the same state.

HELIUM Only hydrogen occurs more often than helium. Helium is also the second simplest of the chemical elements. Its atoms consist of two protons, two neutrons, and two electrons. Only the hydrogen atom is simpler than a helium atom.

Nucleosynthesis A star gains heavier elements by combining its lighter nuclei, hydrogen, deuterium, beryllium, lithium, and boron, which were found in the initial composition of the interstellar medium and hence the star.

Nuclear Fusion The deuterium plus tritium and deuterium plus deuterium reactions are of interest in the development of controlled fusion devices for producing energy. A number of designs have been proposed for these fusion reactors, with most attention given to inertial confinement and magnetic confinement systems.

Formation of the High Mass Elements As time passes the fusion process causes He to accumulate in the core. The increase in the number of He nuclei begins to interfere with the H nuclei collisions and causes a reduction in the rate of H fusion (sometimes called helium poisoning). This reduces the thermal pressure, and the star will begin to contract.

It's a Question of Physics: What's the difference between fission & fusion? Nuclear power plants exploit the process of fission to create energy. The fusion of deuterium with tritium creates helium-4, frees a remaining neutron, and releases energy. Because E=MC 2, when two atoms are fused, a very small amount of mass can be converted into a large amount of energy.

Why does the fusion of hydrogen in stars release energy? And this is where Einstein’s equation comes in. The mass of this helium ‘ash’ is slightly less than that of the original hydrogen nuclei, some of the mass having been released as energy. The difference in mass is very small – amounting to just 0.7 per cent of the mass of the original hydrogen atoms. But, because the ‘conversion factor’, c², is the square of the speed of light and thus a huge quantity, even this small mass difference is enough to release huge amounts of energy per hydrogen atom.

Atomic Bomb question? For Plutonium, the critical mass is more than 6 kg. Fusion: small atoms (or atomic particles) fusing together to form larger atoms. As long as you work with atoms much smaller than iron, you will liberate energy as it takes a bit less binding energy to hold a larger atom than a small one.

Fusion Light nuclei join to form a heavier nucleus. Energy is released in the process. Fusion powers the stars and high yield thermonuclear weapons. Stars begin as a cloud of mostly hydrogen with about 25% helium and heavier elements in smaller quantities. The sun, 107 K core, hydrogen fuses to form helium through a process known as the proton-proton chain (often shortened to the p-p chain). More on stellar fusion in another section of this book.

- Core fusion. 1  Core Fusion--core has shrunk enough to create high enough temperatures to start Helium (or heavier element) fusion. 2  In low mass stars the onset of Helium fusion can be very rapid, producing a burst of energy-helium flash. 3  Eventually it settles down.

What is the equation for a nuclear fusion reaction? Nuclear fission is the process of splitting a nucleus with a large mass into two nuclei with smaller masses. The energy released can then be used to produce electricity.   …Nuclear fusion is the process of merging nuclei with smaller masses into a nucleus with a larger mass.

What is nuclear fusion? The  most common example of nuclear fusion is when two types of (known  as isotopes of) hydrogen fuse together to create helium. The  isotopes of hydrogen deuterium and tritium fuse to create helium.  Deuterium contains one proton and one neutron and tritium contains  two neutrons and one proton.

- One potential solution may be to use helium-3 and deuterium as the fuels in aneutronic (power without neutrons) fusion reactors. The involved nuclear reaction here when helium-3 and deuterium fuse creates normal helium and a proton, which wastes less energy and is easier to contain.

How the Sun Works The pressure is high enough to force atoms of hydrogen to come together in nuclear fusion reactions -- something we try to emulate here on Earth. Two atoms of hydrogen are combined to create helium-4 and energy in several steps:

Nuclear fusion Fusion reactions between light elements, like fission reactions that split heavy elements, release energy because of a key feature of nuclear matter called the binding energy, which can be released through fusion or fission.

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

Fusion - Energy Production in Stars Each line is a possible end-product of the fusion of two normal carbon nuclei (6 neutrons and 6 protons): 1  The first, oxygen and helium products, are endothermic, meaning that it actually requires energy to occur (0.114 MeV). 2  The second line creates neon and helium, and it releases 4.616 MeV of energy.

- That is where there is a sufficient force to fuse them. In order for nuclear fusion to occur, two nuclei must be pushed together against the forces that push them apart. These forces are very large, so it takes an incredible amount of pressure to accomplish this. Because stars are so massive, the necessary pressure is encountered in their core due to gravity.

Main sequence Stars below about 1.5 times the mass of the Sun (or 1.5 solar masses (M☉)) primarily fuse hydrogen atoms together in a series of stages to form helium, a sequence called the proton–proton chain.

Why Nuclear Fusion Is Always 30 Years Away Fusion, at its core, is a simple concept. Take two hydrogen isotopes and smash them together with overwhelming force. The two atoms overcome their natural repulsion and fuse, yielding a reaction that produces an enormous amount of energy.
