Nuclear

Learning Targets Nuclear

1. I can identify elements as stable or unstable based on the ratio of protons to neutrons.
2. I can recall that all elements 83 and above are unstable.
3. I can compare the penetrating power and masses of alpha, beta & gamma as they are emitted during nuclear decay.
4. I can balance nuclear decay reactions with the use of Table N.
5. I can define transmutation as the changing of one atom to another through the change in atomic number.
6. I can differentiate between natural and artificial transmutation.
7. I can identify and define fission and fusion reactions.
8. I can comprehend that nuclear reactions convert mass to a tremendous amount of energy.
9. I can list benefits and risks of fission and fusion reactions.
10. I can identify radioisotopes that are used for medical use as well as dating.
11. I can define half-life as the amount of time it takes for ½ the mass of an unstable radioisotope to decay naturally.

  12.   I can calculate half-life, fraction remaining and original or final masses.
