I keep getting “Bohr's quantised orbits” questions wrong in Atoms. What's the trap?
imagining an electron radiating continuously while remaining in an allowed orbit.
The usual trap: imagining an electron radiating continuously while remaining in an allowed orbit. How to avoid it: no light within an orbit; photon only during a jump. Go back to the definition — Bohr allowed only orbits with angular momentum n h/(2pi). An electron in a stationary orbit does not radiate; light is emitted or absorbed only during a transition.
Key point
Bohr's quantised orbits
Common mistake
imagining an electron radiating continuously while remaining in an allowed orbit.
Memory tip
no light within an orbit; photon only during a jump.
