Question
According to Bohr, what kind of orbits are permitted for electrons?
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.
