Question

The Bohr model for the spectra of a $H$-atom

• A. will not be applicable to hydrogen in the molecular from.
  
• B. is valid only at room temperature.
  
• C. will not be applicable as it is for a $He$-atom.
  
• D. ​​​​​​predicts continuous as well as discrete spectral lines.

Answer 1

Answer: (A), (C)

will not be applicable as it is for a $He$-atom.


According to Bohr model, it is only applicable for $H$-atom and hydrogen like atom (e.g.: $H,H{e}^{+},L{i}^{+2},N{a}^{+1}$ etc.). Bohr model for the spectra of $H$-atom need not be necessary to valid only at room temperature and never predicts continuous as well as discrete spectral lines.

$\text{Final Answer}:$ (a), (b)
