Conceptual Chemistry

Chapter 5: The Atomic Nucleus

Nuclear Fission

Nuclear fission is a process whereby a nucleus splits in half. Only a select number of radioactive elements are fissionable. The chain reaction and the concept of critical mass are also discussed. Duration: 9:48.

Nuclear Fission for Electricity

The heat emitted from the nuclear fission of a U-235 enriched sample of uranium is hot enough to boil water. The steam from this water can be used to turn a turbine to generate electricity. The basic design of an electricity producing nuclear power plant is described. Duration: 4:51.
