
What was the relationship of the flame test lab to the Bohr Atomic Model, what does it help to
prove about this model? (3 pts)

What change in atomic structure accounts for the emission of the visible light observed in the
flame test and in the bright line spectrum of the gas tubes? (4 pts)

Why does every element have its own unique bright-line spectrum? (3 pts)

Explain Bohr’s evidence that allowed him to conclude that the electrons occupy only specific
energy levels? Use explains from the flame test table in your explanation. (4 pts)

Write a brief paragraph explaining how the quantum-mechanical model of electron distribution in
an atom differs from the Bohr model. (3 pts)

Why do you think that many people persist in visualizing the atom according to the out-dated
Bohr model as opposed to accepting the quantum-mechanical model? (3 pts)
