releases large amounts of energy

takes place in the Sun

releases radiation as a waste product

occurs in nuclear power plants and is used to generate electricity

plays a role in the production of essentially all elements heavier than helium.

Answer 1

Check all that apply to fission:

- involves the splitting of nuclei — Yes. Fission is the splitting of a heavy atomic nucleus into lighter nuclei.
- releases large amounts of energy — Yes. Fission releases substantial energy per reaction.
- takes place in the Sun — No. The Sun’s energy comes from nuclear fusion, not fission.
- releases radiation as a waste product — Yes. Fission produces radioactive fission products and emits neutrons/radiation (radioactive waste).
- occurs in nuclear power plants and is used to generate electricity — Yes. Commercial reactors use controlled fission to produce heat and electricity.
- plays a role in the production of essentially all elements heavier than helium — No. Heavier elements are mainly produced by stellar fusion and neutron-capture processes, not by fission.
