Chapter 21: Nuclear Chemistry

Nuclear Chemistry

Nuclear Chemistry – discussion of radiation, nuclear reactions, and half-life, with animated demonstrations of fission, fusion, and chain reactions.

(Main Idea: Radioactive decay leads to more stable nucleons; Half-life is the time for one half of an amount of radioactive nuclei to decay.)

ABC’s of Nuclear Science – introduction to nuclear science, including structure, radioactivity, decay, and more.

(Main Idea: An atom’s mass is less than the masses of its parts; Nuclear reactions affect the nucleus of an atom.)

Atom Builder – Interactive game in which you add protons, neutrons, and electrons to a hydrogen atom to build a carbon atom.  Make sure to keep the charges balanced!

(Main Idea: An atom’s mass is less than the masses of its parts.)

Radioactive Decay

Natural Radioactive Series – animated demonstration of your choice of radioactive decay series, showing the parent material and its change through decay over time.

(Main Idea: Radioactive decay leads to more stable nucleons.)

Radiocarbon Dating

Radiocarbon dating feature, with discussion of carbon-12 and carbon-14 as they occur in nature, and how scientists work with these forms of carbon to carry out radiocarbon dating in the laboratory.

(Main Idea: Radioactivity has surprising applications.)

Nuclear Fission and Nuclear Fusion

Nuclear Fission – interactive activity in which you bombard uranium with neutrons and see the effects, including chain reactions, and take look inside a nuclear reactor!

(Main Idea: In fission, atoms split into nearly equal parts.)

Nuclear Fission and Nuclear Fusion – tutorial on nuclear fission and nuclear fusion.
