Question

Which of the following spectra was not explained by Bohr's Atomic model?

• A. Spectra of single electron system
• B. Hydrogen spectra
• C. Spectra other than Hydrogen like atoms
• D. Spectra of helium atom

Answer 1

Answer: (C), (D)

The correct options are
C Spectra other than Hydrogen like atoms
D Spectra of helium atom

Bohr's model is valid for one electronic system, in hydrogen Bohr's atomic model cannot explain the reasons for Zeeman and Stark effect.In this effect, spectral lines got split into more other lines when magnetic(Zeeman)

and electric field(Stark effect) applied in the system. It is not applicable to the atoms which have more than one electrons.
