CHM 101 Atomic Structure and Quantum Theory Objective Question

Question

According to Bohr, what kind of orbits are permitted for electrons?
Options
A All possible orbits
B Only orbits of certain radii, corresponding to certain definite energies
Correct Answer
C Only elliptical orbits
D Only the largest orbits
Correct Answer

Option B is the correct answer.

Detailed Explanation

Bohr proposed that only orbits of certain radii, corresponding to certain definite energies, are permitted. An electron in an allowed energy state will not radiate energy and will not spiral into the nucleus.

Hint

The notes describe this as a key assumption about permitted orbits.
