Question

Which of the following is not correct about Bohr model of the hydrogen atom?

• A. An electron in an atom could revolve in certain stable orbits without the emission of radiant energy
• B. Electron revolves around the nucleus only in those orbits for which angular momentum $L_{n} = \frac{nh}{2\pi}.$
• C. When electron make a transition from one of its stable orbit to lower orbit then a photon emitted with energy$h\upsilon = E_{f} - E_{i}.$
• D. Bohr model is applicable to all atoms.

Answer 1

Answer: (D)

Bohr model is applicable to all atoms.

Answer 2

The first three options (1), (2) and (3) are Bohr’s postulates of atomic model whereas option (4) is not correct as Bohr’s model is applicable to hydrogen atom only.
