Atoms And Nuclei — NEET/JEE Questions, Notes & Weightage
Class 12 Modern Physics NEET weightage: Medium 1,942 questions
Covers Rutherford's and Bohr's atomic models, energy levels of the hydrogen atom, and spectral series (Lyman, Balmer, etc.). Bohr-model energy-level and spectral-line numericals are this chapter's most consistent NEET/JEE contribution.

Frequently asked questions
What numerical is asked most?
Calculating the energy, wavelength, or frequency of a photon emitted during an electron transition between Bohr energy levels is the chapter's most frequently repeated question type.
Are spectral series (Lyman, Balmer) tested by name?
Yes — identifying which series a given transition belongs to (based on the final energy level) is a common, specific question.
