[edit] Specification

From the OCR GCE Physics A specification. Tick with ✔ when you feel each part of the specification has been covered. Try not to add much more than what is in this list as it would not appear in the exam anyway. Use links to wikipedia for more depth in a topic.

1. Demonstrate a qualitative understanding of the α-particle scattering experiment and the evidence this provides for the existence, charge and small size of the nucleus. ✔
2. Demonstrate a qualitative understanding of X-ray diffraction and the evidence this provides for crystal structure. ✔
3. Demonstrate a qualitative understanding of neutron diffraction and the evidence this provides for crystal structure. ✔
4. Demonstrate a qualitative understanding of electron diffraction and the evidence this provides for the spacing of atoms. ✔
5. Demonstrate a qualitative understanding of high-energy electron scattering and the evidence this provides for the radius of the nucleus. ✔
6. Show an awareness of the relative sizes of nuclei, atoms and molecules.
7. Distinguish between nucleon (mass) number and proton (atomic) number. ✔
8. Understand that an element can exist in various isotopic forms, each with a different number of neutrons.
9. Use the usual notation for the representation of nuclides and represent simple nuclear reactions by nuclear equations.
10. Appreciate the equivalence between mass and energy, and recall and use the equation ∆E = ∆mc2.
11. Appreciate that nuclear processes involve the conservation of charge and of mass-energy.
12. Describe the processes of nuclear fission and nuclear fusion and appreciate that these reactions involve a release of energy.
