Which are aspects covered by Bohr’s atomic model?

A
Electrons can have a measured radius.
B
Higher orbits have lower energies.
C
Electrons exist between orbits.
D
Electrons do not have energy, the energy is determined by the orbit.
4

Describe how the Bohr model explains both of these observations.

Answer:

Electrons can occupy only certain energy levels. When an electron moves from a higher level to a lower one, it emits light at a wavelength determined by the energy difference between the levels. Each element has unique energy levels, so each has a unique emission spectrum.

Did your answer include all of the following?

A
In the Bohr model, electrons can exist only in certain energy levels surrounding the atom.
B
When electrons jump from a higher energy level to a lower one, they emit light at a wavelength that corresponds to the energy difference between the levels.
C
The energy levels in each atom are unique.
6

Compare the modern (electron cloud) model of the atom with Bohr’s atomic model. Which of these statements describe the two models correctly? Check all of the boxes that apply.

A
Bohr’s model was replaced only because of its age.
B
Bohr’s model electrons cannot exist between orbits, but in the electron cloud model the location of the electrons cannot be predicted.
C
The modern model explains all available data about atoms; Bohr’s model does not.
D
The modern model is more widely accepted because it was proposed by more well known scientists.
