Nuclear fusion
Process by which two atomic nuclei join to make a heavier one. This is the type of nuclear reaction that takes place in the centre of stars, for instance in the fusion of hydrogen into helium. It occurs with light elements , of mass less than iron, and it releases energy (i.e.it is an exothermic reaction) because the mass of the product is less than the sum of the two fusing particles; the mass defect (lost mass) is turned into energy according the famous E = m c2 equation.

Nuclear fusion
A nuclear process whereby several small nuclei are combined to make a larger one whose mass is slightly smaller than the sum of the small ones. The difference in mass is converted to energy by Einstein's famous equivalence E=mc2. This is the source of the Sun's energy and, ultimately, of (almost) all energy on Earth.

nuclear fusion (fusion)
Compare with nuclear fission .Combination of two smaller nuclei to form a larger nucleus. The larger nucleus has higher binding energy per nucleon than the original nuclei, and fusion results in the release of energy.

Nuclear fusion
In physics and nuclear chemistry, nuclear fusion is the process by which multiple atomic particles join together to form a heavier nucleus. It is accompanied by the release or absorption of energy. 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. Nuclear fusion is naturally found in stars.
