Bohr's Model Limitations?

📌 CONCEPT: The Bohr's model limitations refer to the inability of the model to explain certain atomic phenomena, such as the presence of isotopes and the energy absorption spectra of atoms.

📐 RULE / FORMULA: The Bohr's model failed to account for isotopes due to the existence of different atomic masses in atoms of the same element.

💡 WORKED EXAMPLE: Consider the atomic masses of Carbon-12 and Carbon-13. The Bohr's model could not explain the existence of these isotopes, which was a significant limitation. This led to the development of later models, such as the Quantum Mechanical Model.

⚠️ COMMON MISTAKE: Students often confuse the Bohr's model with the Quantum Mechanical Model, which resolved the limitations of the former. However, the Bohr's model was a significant step towards the development of more advanced atomic models.
