Question

limitations of bohr model and

Answer 1

BOHR'S MODEL EXPLAINS ALL THE LINE SPECTRA OBSERVED IN CASE OF HYDROGEN ATOM . IT IS A SUCCESSFUL MODEL AS FAR AS LINE SPECTRA OF HYDROGEN ATOM IS CONCERNED.

BUT THE LINE SPECTRUM OF HYDROGEN WHEN OBSERVED THROUGH A HIGH RESOLUTION SPECTROSCOPE APPEARS AS GROUPS OF FINER LINES.

BOHR'S ATOMIC MODEL FAILED  TO   ACCOUNT FOR SPLITTING OF LINE SPECTRUM.

Answer 2

1. Bohr's model could not explain the two closely spaced lines in the hydrogen spectrum.

2. Bohr' model could not explain the spectra of atoms other than hydrogen, for
    example, that of helium.

3. It Could not explain the splitting of spectral lines of hydrogen atoms due to
    presence of magnetic fields and electric fields.  That is, Bohr's model
    could not explain the Zeeman effect and Stark effect.

4. It could not explain how atoms form chemical bonds.
