it is called natural radioactivity
When large unstable nuclei split because the electric for is greater than the nuclear force is nuclear decay.
Nuclear decay
is it Nuclear physics, artificial transmutation, natural radioactivity, nucleus, or artificial radioactivity i think it is nuclear physics dont hold me accountable though
Nuclear fission
radioactive decay
The process which describes the splitting of a large unstable atom into two intermediate size atoms and extra neutrons is called nuclear fission. Nuclear fission is a nuclear reaction or a radioactive decay process.
This process through which unstable nuclei emit radiation is called radioactive decay. It also is called nuclear decay, and it is a natural process in which an atom of an isotope decomposes into a new element.
Nuclear fission
nuclear fusion
radioactive decay
Fission to be more specific its nuclear fission...
The process is called decay, or sometimes nuclear decay. A link can be found below.
