Bohr Model Assessment Form
Evaluate your understanding of the Bohr model with this short assessment. Please answer all questions thoughtfully.
Which scientist proposed the Bohr model of the atom?
*
Niels Bohr
Ernest Rutherford
J.J. Thomson
James Chadwick
According to the Bohr model, where are electrons found?
*
In fixed orbits around the nucleus
Randomly scattered throughout the atom
Inside the nucleus
In continuous clouds
Which of the following best describes an energy level in the Bohr model?
*
A specific distance from the nucleus where electrons can exist
An area with no electrons
A random position in the atom
A location inside the nucleus
How does the Bohr model explain the emission of light by atoms?
*
Electrons jump between energy levels, emitting photons
Protons emit light as they move
Electrons merge with neutrons
Atoms absorb light and release it randomly
Indicate your level of agreement: The Bohr model accurately describes all aspects of atomic structure.
