Discuss the limitations of Rutherford's nuclear model of the atom that led to the development of Bohr's model.
ChemistryClass 9CBSEAnswered 12 May 2026
Answer
Rutherford's model could not explain why electrons orbiting the nucleus didn't continuously lose energy and spiral into the nucleus, causing the atom to collapse. It also failed to explain the discrete line spectra observed for elements, suggesting electrons could only exist in specific energy levels.
