QUESTIONS AND CORRECT ANSWERS| GRADED A+ | 2025 LATEST
VERSION | 100% VERIFIED
Observations/ theories supporting the wave nature of light - (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 - (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 - (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 - (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 -
(answer)l
0 to n-1
The shape of the orbital, also known as the subshell
