Read each question carefully and answer to the best of your ability. Refer to your notes and textbook as needed.
1. Which of the following is NOT a postulate of Bohr's atomic model?
Electrons orbit the nucleus in fixed energy levels.
Electrons can jump between energy levels by absorbing or emitting photons.
Electrons behave as both particles and waves.
The energy of an electron in an orbit is quantized.
2. What is the maximum number of electrons that can occupy the third energy level (n=3) in the Bohr model?
