- Students know the nucleus of the atom is much smaller than the atom yet contains most of its mass.
- Students know protons and neutrons in the nucleus are held together by nuclear forces that overcome the electromagnetic repulsion between the protons.
|
|
- Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. (this will include knowing the relationships between # of protons, Atomic number, mass #, # electrons, and # of neutrons)
|
|
- Students know the three most common forms of radioactive decay (alpha, beta, and gamma) and know how the nucleus changes in each type of decay.
- Students know alpha, beta, and gamma radiation produce different amounts and kinds of damage in matter and have different penetrations.
|
|
- Students know the energy release per gram of material is much larger in nuclear fusion or fission reactions than in chemical reactions. The change in mass (calculated by E = mc2) is small but significant in nuclear reactions.
- Students know some naturally occurring isotopes of elements are radioactive, as are isotopes formed in nuclear reactions.
|
- These are facts, presented in class. If you did not copy them down, learn them from here:
- In nuclear reactions, small amount of mass are converted to large amounts of energy. The energy change is much greater per unit of mass than in chemical reactions.
- Some naturally isotopes are radioactive.
- All man-made isotopes are radioactive.
