There are two: Nuclear Fission and Nuclear Fusion. Fission is when a neutron is fired at an element with a high atomic number (usually Uranium) which then splits, releasing energy and more neutrons. this produces a chain reaction, which continues until all nuclei have been split. Fusion occurs in stars and a few experimental reactors, and happens when two forms of Hydrogen nuclei (Deuterium and Tritium) fuse into an unstable nucleus, which in turn splits again into Helium and a spare neutron. Fission can start at any temperature, but Fusion only when Hydrogen is in a plasma state.
Nuclear energy is formed by either nuclear fusion or nuclear fission. Nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. Nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts.
Nuclear energy uses the fission energy.
yes
All the elements after Uranium(atomic no. 92) have been artificially produced.
Elements that have greater atomic masses then uranium are created using nuclear fission.
Most energy is produced by the breaking and reforming of molecular bonds. A car's combustion reaction in which fuel is converted into energy, co2 and water is a good example of this. Energy is rarely produced on the atomic level, such as a nuclear power plant or an atom bomb. Energy is produced this way through Einstein's E=mc^2. In an atomic reaction the mass of the products is slightly less then the mass of the reactants. Plug the change in mass into Einstein's equation and you get a lot of energy. To recap, most energy is made on the molecular level with endothermic (reactions which absorb energy) and exothermic reactions (reactions which emit energy), however a small amount takes place on the atomic level.
it is equal to the difference of mass between the products and the reactants multiplied by the square of the speed of light in vaccum. (infact it is well apllicable to chemical reactions also where only small differences in masses are involved.) NOTE:- the enery released or absorbed depends o whether the products are lighter ot heavier than the reactants. Famous Eintiens enery equivalent of mass * E=mc^2 *~
The term nuclear reaction is a general one, and it refers to any change in atomic nuclei. There are a lot of different ones (nuclear changes) that qualify, so let's look at some. A nuclear reaction could be a nuclear decay event where a single atomic nucleus undergoes a change. Alpha decay, beta decay, spontaneous fission and even gamma emission are nuclear reactions. Additionally, a nuclear reaction could refer to the interaction of a subatomic particle and an atomic nucleus, like neutron capture in nuclear chain reactions. Further, nuclear fusion, which is constantly going on in our sun, is also considered a nuclear reaction because lighter atomic nuclei are fused together to make heavier ones. As there are a number of "flavors" of nuclear reactions, we leave a reader a variety of options to choose from when we apply this term. It may help to be more specific, depending on the way this term is used.
Nuclear reactions in a nuclear reactor are controlled reactions. The reactions in the atomic bomb are not controlled reactions

Nuclear fission is when a neutron is fired at an element with a high atomic number, which splits and releases more neutrons and energy as a result. Nuclear fusion occurs in stars and experimental reactors.

The scientific term for nuclear energy is "nuclear power." This energy is produced through reactions in the atomic nucleus, specifically through processes like nuclear fission or fusion to generate heat that can be converted into electricity.
An atomic weapon is an alternative name for a nuclear weapon, a weapon which derives its energy from the nuclear reactions of either fusion or fission.
Nuclear weapon, nuclear (atomic) power stations. Also the Sun works on nuclear reactions.
Atomic nuclei are changed by nuclear reactions or radioactive disintegration.
What happens is the nuclear bomb explodes and something like gas comes from it and it disinigrates you
NO!!! 'Atomic' is an adjective, e.g. Atomic Mass.
Nuclear Reaction.
Yes, the decay of unstable atomic nuclei is the source of nuclear radiation.
