Defects of Bohar atomic model.

   Defects of the Bohr atomic model.

                             

 .1

i. It does not explain the spectrum of polyelectron system.

ii. it explains the spectrum of the hydrogen atom and ions having one electron.

  2.

iii.it does not explain the fine structure of the Hydrogen atom.

  3.

 iv. It explains the only single plane motion of the electron. But in fact electron motion take place in three dimensions.

   4.

v. It does not explain the Stark and Zeeman effect.
