Final answer:

Bohr's atomic model was replaced by the modern atomic model due to limitations in predicting spectra for larger atoms and explaining electron orbits.


Explanation:

Bohr's atomic model was replaced by the modern atomic model due to several reasons. One key factor was that Bohr's model could not correctly predict the emission spectrum for larger atoms, beyond hydrogen and one-electron ions. Additionally, it could not explain why electrons only orbited at fixed distances and not in between, leading to the need for a revision in scientists' understanding of matter.
