Draw Backs of Bohr's Atomic Model
Category : JEE Main & Advanced
(1) It is valid only for one electron atoms, e.g. : \[H,\,H{{e}^{+}},\,L{{i}^{+2}},\,N{{a}^{+1}}\] etc.
(2) Orbits were taken as circular but according to Sommerfield these are elliptical.
(3) Intensity of spectral lines could not be explained.
(4) Nucleus was taken as stationary but it also rotates on its own axis.
(5) It could not be explained the minute structure in spectrum line.
(6) This does not explain the Zeeman effect (splitting up of spectral lines in magnetic field) and Stark effect (splitting up in electric field)
(7) This does not explain the doublets in the spectrum of some of the atoms like sodium \[(5890\,\overset{\text{o}}{\mathop{\text{A}}}\,\,\And 5896\,\overset{\text{o}}{\mathop{\text{A}}}\,)\]
