Atomic Structure - Creating Quantum Theory - Photoelectric Effect
5 important questions on Atomic Structure - Creating Quantum Theory - Photoelectric Effect
What is the photoelectric effect?
- red light - no effect
- blue light - causes e- motion
Why does dim blue light let e-s flow but not intense red light?
- matter cannot occupy same place or space as another
- 1 photon of light can strike the sodium panel @ particular area @ a time due to space requirements
What is cont. Spectrum?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is an electron transition?
What were the problems w/ Bohr's Model?
- in multi-electron atoms you find clusters of closely packed spectral lines in same colour region
- MORE diff line spectra to determine Bohr's theory
2. Idea of e-s travelling in shells suggested tht exact location of an e- in an atom could be found - BUT NOT TRUE (proven by Heisenberg)
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
