Write out a correct version of:
"the fuel in a nuclear power station is hydrogen gas"

"the fuel in a nuclear power station is Uranium 235"

Explanation:

Nuclear fuel is one of the sources of energy. Nuclear fission is the method used to create nuclear energy. Nuclear fission is defined as the breaking down of the helium atoms to hydrogen which produces large amounts of energy. There is one method of preparing nuclear energy which is nuclear fusion. It is the fusion of four hydrogen atoms to form one helium atom. It happens only in the Sun. It produces a larger amount of energy than fissionThe fuel used in a nuclear power station is Uranium 235 and plutonium 239 and these are the radioactive metals.

Alkaline earth metals are found in group 2 of the periodic table.
