The source of power in a nuclear power plant comes from a) burning hydrogen atoms. b) reacting uranium atoms. c) splitting uranium nuclei. d) combining hydrogen nuclei.

C) splitting uranium nuclei

Explanation:

Nuclear energy is the energy that is obtained by manipulating the internal structure of atoms, usually useful to produce electricity.

This type of energy can be obtained by nuclear fusion and by nuclear fission:

In nuclear fusion, the energy is released when the atoms combine or fuse to form a larger atom. The sun produces heat energy in this way, however, this procedure is not used to produce nuclear energy, although it is in the process of development, since the function, by itself a quantum process, can not be controlled with the existing technology. In nuclear fission, atoms separate to form smaller atoms, releasing energy. This process is used in nuclear power plants to produce electricity.

So, the source of power in a nuclear power plant comes from splitting uranium nuclei, since when a nuclear fission (or a nuclear fusion) occurs, the atoms experience a slight loss of mass, which becomes a large amount of heat energy.

The answer is c because fusion is way more dangerous and complicated and extremely hard to do, so they rely on fission, the splitting of atoms

You know how the first one if filled up like the objects do the same but with the other categories

I’m not sure what your trying to say here.. can you clarify again?
