Nuclear transmutation occurs in any process where the number of protons or neutrons in the nucleus of an atom is changed.. A transmutation can be achieved either by nuclear reactions (in which an outside particle reacts with a nucleus) or by radioactive decay, The following is a list of states that have admitted the possession of nuclear weapons or are presumed to possess them, the approximate number of warheads under their control, and the year they tested their first weapon and their force configuration. This occurs by physical and chemical manipulations usually involving one or more reactions. Nuclear fission splits a heavy nucleus such as uranium or plutonium into two lighter nuclei, which are called fission products. Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons).The difference in mass between the reactants and products is manifested as either the release or absorption of energy.This difference in mass arises due to the difference in nuclear binding energy between Conservation of mass In modern laboratory uses, the process is reproducible and reliable.. A chemical synthesis involves one or more compounds (known as Nuclear transmutation is the conversion of an atom of one element into an atom of another element through nuclear reactions.
