CHAPTER 4 TEST REVIEW GUIDE
Students should be able to:
1. Explain why electromagnetic radiation is thought of as having dual nature.
2. Identify observations or characteristics of light that are best explained by a wave nature
and those that are best explained by a particle nature.
3. Explain the relationship between wavelength, frequency and energy
4. An element’s fingerprint is called a _______ _______ _________
5. Explain how the line-emission (bright-line) spectrum of hydrogen is produced
according to the Bohr model of the atom. How is a photon produced? Be able to
produce the Bohr model.
6. Describe the shortcomings (2) of Bohr’s model as well as what the Bohr model gave us
(3) (what was beneficial).
7. What is the difference between the Bohr model and the Quantum-Mechanical Model.
ORBIT -> ORBITAL
7a. Explain the contributions of DeBroglie, Heisenberg and Schrodinger to our current
understanding of the atom (quantum-mechanical model).
8. Explain what an orbital is and how it is fundamentally different from an orbit.
9. List the information provided by each of the four quantum numbers.
What do they mean??? Where are they located on the periodic table???
Understand how we constructed the table in class, were the combinations of
numbers come from, etc.
10. Identify each of the three rules for writing electron configurations.
11. Read electron configurations (all three styles) and identify what each of the symbols
represents (ex. 1S22S1…).
Know how to use the Periodic Table to produce and read electron configurations.
12. Write electron configurations for selected elements in each of the three styles of
notation (orbital diagram, complete electron configuration and noble gas notation).
13. Identify the highest occupied energy level and the number of electrons found there
when given an electron configuration.
14. When given only the outer shell configuration, identify the period and group
location of the element (ex. …4S24P4… which group? ... period?).
15. Calculate the frequency and wavelength and energy of electromagnetic radiation and
photons.
16. Understand the photoelectric effect.
17. Understand the purpose and idea’s of the Spectroscope and Flame Lab.
