What type of fuel is produced from the splitting of atoms?

The production of fuel from the splitting of atoms is specifically associated with nuclear fuel. This process involves nuclear fission, where atomic nuclei, typically those of heavy elements like uranium or plutonium, are split into smaller parts. This splitting releases a significant amount of energy, which can be harnessed for electricity generation in nuclear reactors.

Nuclear fuel is distinct from other types of fuels. Biomass fuel is derived from organic materials, fossil fuel comes from ancient biological matter that has been subjected to heat and pressure over millions of years, and solar energy is generated from the sun's radiation, not through atomic reactions. Understanding the differences between these fuel types helps to clarify why nuclear fuel is the appropriate answer, as it directly relates to the splitting of atoms.
