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?
2
8
18
32
3. In the Bohr model, electrons occupy specific energy levels or around the nucleus.
4. When an electron moves from a higher energy level to a lower energy level, it energy in the form of a photon.
5. Describe one major limitation of the Bohr model of the atom.
6. Observe the Bohr model of an atom below. Identify the nucleus and the electron shells.
a) Label the nucleus in the diagram.
b) How many electron shells are shown in this model?
7. The Bohr model accurately explains the spectra of multi-electron atoms.
