Document Summary
An atomic review: atoms have subatomic particles, electrons are in the orbit; neutrons and protons are in the nucleus, this is where nuclear energy comes from. Isotopes: we know that the number of protons makes each element unique, sometimes an atom can have an atypical (and less stable) number of neutrons. Isotope: an atom with the right number of protons but the wrong (atypical/less stable) number of neutrons. Nuclear fission: this splitting of unstable isotopes is called fission, the atom splits into 2 new atoms. Nuclear fission chain reaction: this nuclear fission chain reaction can happen in a matter of seconds with only a tiny amount (a couple of pounds) of starting material: Electricity is generated by electric generators: michael faraday invented generators in 1831, an electric generator: a coil of wire that rotates in a magnetic field. Or a stationary wire within a rotating magnetic field. Various ways to get the coil to rotate:
