Question

Limitations of BOHR'S atomic model​

Answer 1

Answer:

Limitations of the Bohr Model

The Bohr Model was an important step in the development of atomic theory. However, it has several limitations.

•    It is in violation of the Heisenberg Uncertainty Principle.  The Bohr Model considers electrons to have both a known radius and orbit, which is impossible according to Heisenberg.

•    The Bohr Model is very limited in terms of size.  Poor spectral predictions are obtained when larger atoms are in question.

•    It cannot predict the relative intensities of spectral lines.

•    It does not explain the Zeeman Effect, when the spectral line is split into several components in the presence of a magnetic field.

•    The Bohr Model does not account for the fact that accelerating electrons do not emit electromagnetic radiation.

Answer 2

Explanation:

bohr model of atom:-)

• electrons revolve around the nucleus in a definite energy level of shell
• electrons are stationary.
• only those orbits can permitted which have angular momentum value equals to mvr=nh/2pei

limitations of bohr model:-)

• it does not explain spectrum of multi electron atom
• it does not explain why angular momentum related to nh/2pie
• it does not explain the effect of electric field on magnetic field on hydrogen spectrum
• it does not explain uncertainty in position and velocity of electron which can be explained by Heisenberg principle
• it does not explain about dual nature of matter explain by de Broglie.
