What is nuclear fission?
O A. The joining of nuclei
B. The gain of nuclear mass
O C. The splitting of a nucleus
O D. The formation of an ion
Explanation:
C is the correct answer i.e. splitting of a nucleus
The splitting of a nucleus is known as the nuclear fission. So option C is correct.
Nuclear fission is the process of splitting an atom’s nucleus into lighter nuclei. This can occur naturally through radioactive decay, or it can be simulated in a laboratory by achieving the necessary conditions (e.g. neutrinos being bombarded). The resulting fragments usually have a mass that is less than that of the original nucleus.
We use the fission reaction in nuclear reactors to create electricity. The heat generated by the fission reaction is converted into a working fluid that passes through a steam turbine. The working fluid then drives a ship's propellers or turns the shafts of electrical generators.
