Bohr Model Limitations – Rankers Physics

Atomic Structure: Practice Problem & Solution

Assertion (A): Bohr model can explain spectra of hydrogen or hydrogen like species. Reason (R): Bohr model is the best atomic model.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution Explained:

To solve this problem, we apply the core principles of Atomic Structure. Understanding the underlying formula is key to arriving at the correct answer below:

Bohr's model successfully explains the spectra of hydrogen and hydrogen-like atoms. However, it fails for multi-electron atoms, cannot explain fine structure or the Zeeman effect, and is superseded by quantum mechanics. Therefore, it is not the best atomic model.
