what is nuclear fusion?

Answer 1

Preparation for nuclear devices.

Answer 2

In physics and nuclear chemistry, nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy depending on the masses of the nuclei involved. Iron and nickel nuclei have the largest binding energies per nucleon of all nuclei and therefore are the most stable. The fusion of two nuclei lighter than iron or nickel generally releases energy while the fusion of nuclei heavier than iron or nickel absorbs energy; vice-versa for the reverse process, nuclear fission.

Answer 4

Nuclear fusion, in broad terms, is the joining of two or more atomic nuclei into a single nucleus. More specifically, nuclear fusion typically refers to combining four hydrogen nuclei into a single helium nuclei, During this process, a portion of the combining nuclei's mass is converted to electromagnetic energy, resulting in a single nucleus that masses less than its components coupled with a release of high-energy photons.. Fusion is not limited to hydrogen-to-helium, however. Elements fused up to iron result in a release of energy. Fusing elements that result in an nuclei heavier than iron's requires an energy input, but are thought to occur in the heart of stars where energy is plentiful.

Waxing philosophically, fusion is an awesome subject. Current theory states that every non-hydrogen atom in the universe was created through fusion, some in the big bang but most in the heart of a star. This means that you and I, being mainly composed of atoms heavier than hydrogen, contain within ourselves elements released by an exploded star. Wicked cool.

Answer 5

Nuclear fusion is the process in which two nuclei of atoms combines under pressure and temperature to release a high amount of energy in form of light and heat.

Protium and deutrium (Hydrogren isotopes) takes part in fusion reaction.

Answer 6

Nuclear fusion is the process in which two lighter nuclei combones to form a heavy nucleus.

Answer 7

When the environment is conducive that is at the right temperature , pressure , gravitational force , when the atoms are bombarding each other at the right velocities, nuclei of two atoms combine to form a third atom having a bigger nuclei with some loss of mass and enormous release of energy, The energy released is given by the famous Einstien equation that is E=mc^2 where m is the mass converted into energy , c is the speed of light.

Answer 8

"nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy depending on the masses of the nuclei involved."

Answer 9

nuclear fusion reaction is wen lighter nuclei combine to form heavy nuclei and a large amount of energy is produced this reaction has not been controlled on earth but only in the sun . In sun lighter nuclei (that is hydrogen) combine to form heavier nuclei (that is helium).

Answer 10

Nuclear fusion is the nuclear catalyst that causes two atoms to fuse.

Answer 11

The fusion of hydrogen atoms (like the sun). The opposite is Nuclear Fission (used for atomic bombs)
