Atomic energy is generated by splitting the nucleus of a:
Show answer Hide answer
Answer: C. Radioactive atom
Explanation
Atomic energy is generated by splitting the nucleus of a radioactive atom. Nuclear fission releases immense binding energy when heavy atomic nuclei divide. The radioactive atom serves as the foundational fuel source for nuclear power. Uranium and plutonium isotopes are commonly used elements in nuclear fission reactors. Bombardment with neutrons triggers the unstable nucleus to split into smaller fragments. This chain reaction produces heat used to generate electricity in power plants.
Nuclear power plants provide low-carbon electricity to meet growing global energy demands. Physics students study nuclear reactions to understand mass-energy equivalence principles. Safety protocols govern the handling and storage of spent radioactive fuel materials. Option A refers generally to an element, which lacks the specific atomic focus. Option B mentions a cell, which is a biological unit unrelated to nuclear physics. Option D describes a general substance, whereas fission specifically targets individual atoms.
