Question

what is the diffrene between nuclear fusion and nulclear fission

Answer 1

Both fission and fusion are nuclearreactions that produce energy, but the applications are not the same. Fissionis the splitting of a heavy, unstable nucleus into two lighter nuclei, andfusion is the process where two light nuclei combine together releasing vast amounts of energy.

Answer 2

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a large amount of energy.
nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus.
