To determine

To Explain: Limitations of Bohr’s Atomic Model.

Explanation of Solution

Introduction:

• Bohr’s model of hydrogen atom describes that electrons travel in specific shells around the nucleus.
• Energy of each shell n is:

  $E\left(n\right)=\frac{-1}{n^2}\times 13.6\text{eV}$

Shortcomings of Bohr’s model are:

• Bohr could not explain or predict the behaviour of other atoms.
• There was no information regarding the arrangement and distribution of electrons within the atom.
• There was no explanation regarding the observed variations in intensity of the spectral lines of an element.
