Demerits of bohr atomic model in simple words
Answers
The demerits of Borh's atomic model are-
1.The theory could not account for the spectra of atoms more complex than hydrogen.
2.The theory does not give any information regarding the distribution and arrangement of electrons in an atom.
2. It doesn't explain, the experimentally observed variation in the intensity of the spectral lines of the element.
3. When the spectral line of a hydrogen atom is examined by spectrometers having high-resolution power, it is found that a single line is composed of two or more close components. This is known as the fine structure of spectral lines. Bohr's theory could not account for the fine structure of spectral lines.
4.It is found that when electric or magnetic filed is applied to an atom, each of the spectral line split into several lines. The former effect is called as Stark effect, while the latter is known as Zeeman effect. Bohr's theory could not explain the Stark and Zeeman effects.
