Drawbacks of Thomson Atomic Model

Drawbacks


  1. According  to  electromagnetic  theory,  the  vibrating  electron should  radiate  energy  and  the  frequency  of  the  emitted  spectral  line should  be  the  same  as  the  electron.  In  the  case  of  hydrogen  atom, Thomson’s model gives only one spectral line of about 1300 Å. But the experimental  observations  reveal  that  hydrogen  spectrum  consists  of five  different  series  with  several  lines  in  each  series.
  2. It  could  not  account  for  the  scattering  of  α-particles  through large  angles
