For example plutonium is a nuclear fuel; also the isotope 233U.
The artificially made elements on the Periodic Table are all radioactive substances, such as technetium and curium, which have important applications in the fields of nuclear medicine, space travel, and nuclear energy research, among others.
Nuclear Energy is made up of atoms that can be naturally made or man made.
When we obtain nuclear energy from elements in the earth like Uranium, what we are doing, is obtaining energy which produced by splitting up subatomic particles. So we obtain the atomic energy from splitting up the atomic particles, not from the uranium itself, which is a natural resource. Since the splitting up of subatomic particles is completely "man-made", if you will and does not occur in the environment, Nuclear energy is a man made resource
Synthetic elements are obtained by nuclear reactions.
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
All elements heavier than iron are made by nuclear reactions that consume energy rather than producing it, so the universe that you describe would have no heavy elements.
Where: In supernovae. How: by nuclear fusion.
nuclear energy is a type of energy made by splitting atoms when the atoms split they make energy
in nuclear reactors and particle accelerators
No.
Very important, out body is made of compounds, which are in turn made of elements.
