What does “Bohr's quantised orbits” actually mean in Atoms, and why does it matter for NEET?

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.

In simple words: 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. Getting Bohr's quantised orbits clear matters because NEET questions on Atoms usually test this idea directly, not just a formula you memorised.

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.
