What to Focus On
- Cathode rays consist of negatively charged electrons
- Thomson's e/m ratio = 1.758820 × 10¹¹ C kg⁻¹
- Millikan determined electron charge = -1.6 × 10⁻¹⁹ C
- Thomson model: electrons embedded in positive sphere
- Rutherford's experiment proved nuclear model
- Most atomic space is empty
- c = νλ relationship for electromagnetic waves
- Energy is quantized: E = nhν
- Photoelectric effect proves particle nature of light
Common Mistakes to Avoid
Electrons revolve around the nucleus in fixed circular orbits like planets around the sun
Energy levels are equally spaced - the energy difference between n=1 to n=2 is the same as n=2 to n=3
Quantum numbers can have any values as long as they are integers
