Question 1.
What is the main assumption of the Bohr model?
Show hintHide hint
Think about how the model describes electron movement.
Question 2.
What does the Balmer series refer to?
Show hintHide hint
Consider what happens when electrons drop to this specific level.
3Question 3.
What did the Bohr model successfully predict about hydrogen's spectral lines?
- They are continuous.
- They are discrete and quantized.
- They cannot be predicted.
Show hintHide hint
Think about the nature of energies in atomic systems.
4Question 4.
True or False: The Rydberg constant applies only to hydrogen.
- True
- False
Show hintHide hint
Consider whether it can apply to other simple systems.
Question 5.
Given that the wavelength of light emitted when an electron transitions from n=4 to n=2 in hydrogen is known, derive the energy change this transition represents.
Show hintHide hint
Remember to convert the wavelength into meters.
Question 6.
Discuss why the Bohr model's predictions for helium differ from observed spectra. Provide a theoretical explanation.
Show hintHide hint
Consider the implications of additional electrons.
