Question

State whether True or False :

Bohr's model failed to explain atomic spectra of multi-electron atoms.

• A. True
• B. False

Answer 1

The correct option is A True

Limitations of Bohr Model :

• Bohr's theory does not explain the spectrum of a multi-electron atom.
• 
  
• Bohr interrelates quantum theory of radiation and classical law of physics without any theoretical explanation. This was the biggest drawback of this model.
• 
  
• Bohr's theory does not explain the fine structure of the spectral lines. Fine structure of the spectral line is obtained when a spectrum is viewed by spectroscopy of more resolution power.
• 
  
• Bohr theory does not explain the splitting of spectral lines in the presence of a magnetic field (Zeman's effect) or electric field (Stark's effect).

Therefore, the given statement is true.
