i think it is uranium
The most useful is of course Uranium.
There are four types of nuclear reactions. Fusion Fission Radioactive Decay Artificial Transmutation
sun, fusion of hydrogen nuclei making helium nuclei (not radioactive)nuclear reactor, fission of uranium nuclei making a wide variety of different fission product isotopes having mass numbers from 72 to 161 (all very radioactive)
Plutonium is not related to uranium isotopes radioactive decay; plutonium is obtained by nuclear reactions from uranium isotopes only in nuclear reactors.
Plutonium is an artificial chemical element, radioactive, unstable, toxic, solid, metal, member of the actinides group, Olivette very important for nuclear weapons and nuclear fuels, etc.
When one element goes through radio active decay, it looses some alpha , beta particles and also neutrons so considering those things we should reduce number of alpha , beta and also neutrons lost by the element. from that we have to decide the element which occur after radio active decay.
According to Dalton's atomic theory chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction (it is possible only during nuclear reactions and radioactive disintegration).
Transmutation of elements refers to the conversion of one chemical element into another. This occurs in nuclear reactions or through radioactive decay.
The radioactive element is composed of unstable nuclei that try to reach stability through emitting nuclear radiations as alpha, beta, and gamma nuclear radiations.
- radioactive decay - nuclear fission - nuclear reactions
There are four types of nuclear reactions. Fusion Fission Radioactive Decay Artificial Transmutation
Radioactive waste.
Polonium is a radioactive chemical element, extremely rare, accompanying uranium in some ores; now polonium is obtained by nuclear reactions.
weak force
Radioactive reaction is a red-ox reaction. This is a nuclear decay.
Nobelium is an artificial chemical element, radioactive, unstable, atomic number 102, member of the actinoids family, obtained by nuclear reactions only in infinitesimal quantities, etc.
Uranium
Polonium is a radioactive chemical element.
