Standard 11: Nuclear Processes - 3% of Star Exam
Nuclear processes are those in which an atomic nucleus changes, including radioactive decay of naturally occurring and human-made isotopes, nuclear fission, and nuclear fusion. As a basis for understanding this concept:
State Standard:
Protons and neutrons in the nucleus are held together by strong nuclear forces which are stronger than the electromagnet repulsion between the protons. |
Students Will Be Able To:
Compare and contrast the electrostatic force to the nuclear force. |
State Standard:
The energy release per gram of material is much larger in nuclear fusion or fission reactions than in chemicals reactions: change in mass (calculated by E=mc2) is small but significant in nuclear reactions. |
Students Will Be Able To:
Compare the amount of energy involved in a nuclear reaction to that of a chemical reaction, using E=mc2 |
State Standard:
Many naturally occurring isotopes of elements are radioactive, as are isotopes formed in nuclear reactions. |
Students Will Be Able To:
Define radioactivity and radioactive isotopes. |
State Standard:
The three most common forms of radioactive decay (alpha, beta, gamma) and how the nucleus changes in each type of decay. |
Students Will Be Able To:
Define and classify each type of radioactive decay. |
State Standard:
Alpha, beta, and gamma radiation produce different amounts and kinds of damage in mater and have different penetrations. |
Students Will Be Able To:
Compare the damage and penetration of the three types of radioactive decay. I&E (12E): Solve scientific problems using quadratic equations, and simple trigonometric, exponential, and logarithmic functions. |
State Standard:
How to calculate the amount of a radioactive substance remaining after an integral number of half lives have passed. |
Students Will Be Able To:
|
State Standard:
Protons and neutrons have substructure and consist of particles called quarks. |
Students Will Be Able To:
|
