Question 661
Which of the following statements is INCORRECT about the Bohr atomic model?
Correct Answer Logic:
Bohr's model limitations:
Option (2) is the wrong statement about a fault — it is actually a correct criticism. But among the options, the model does not account for electron wave-particle duality (option 4 — this is attributed to de Broglie, not Bohr).
Actually, option (2) is a true limitation: Bohr assumed definite orbits (fixed position and velocity), which directly violates Heisenberg's uncertainty principle. The correct answer marked is (2) as the false premise Bohr made. Bohr's model is also unable to explain Zeeman/Stark effects or multi-electron atoms.
