Chem 103 Module 2 ACTUAL Exam
Questions and CORRECT Answers
Observations/ theories supporting the wave nature of light - CORRECT ANSWER --
optical phenomena such as reflection/ refraction
- light passing through narrow, closely spaced slits produces interference patterns
- James Clerk Maxwell's theory of electromagnetic radiation
Observations/ theories supporting the particle nature of light - CORRECT ANSWER --
Newton's law of motion (light was streams of extremely tiny particles traveling at high speeds
according to his laws of motion)
- photoelectric effect
- blackbody radiation
3 main features of the Bohr model that apply to all models - CORRECT ANSWER -1. The
energies of electrons in an atom are quantized
2. An electron's energy increases with increasing distance from the nucleus.
3. The discrete energies of light emitted by elements in an excited state result from quantized
electronic energies.
Symbol, allowed values, and meaning of principal quantum number - CORRECT
ANSWER -n
1 to infinity
Specifies the shell an electron occupies in an atom
Symbol, allowed values, and meaning of secondary (angular momentum) quantum number -
CORRECT ANSWER -l
0 to n-1
The shape of the orbital, also known as the subshell
