Question 13 • EO Night School Chemistry 7320A

How did Niels Bohr describe electrons in his atomic model?

Answer
A
Their energies can have any values.
B
Their exact positions cannot be known.
C
They have high probability to be found in certain regions.
D
They orbit the central nucleus in discrete paths.

Explanation

In Bohr’s atomic model, electrons move around the central nucleus in specific, discrete orbits, each with a particular energy. So the correct choice is “They orbit the central nucleus in discrete paths.” The idea that electrons are most likely found in certain regions describes the later quantum-mechanical model, not Bohr’s model.
