Nuclei — NEET/JEE Questions, Notes & Weightage
Class 12 Modern Physics NEET weightage: Medium 0 questions
Covers nuclear structure, mass defect and binding energy, radioactivity (decay laws, half-life), and nuclear reactions (fission/fusion). Half-life and binding-energy numericals are tested almost every year.

Frequently asked questions
What is the most common numerical type?
Radioactive decay numericals — finding remaining quantity, decay constant, or half-life using the exponential decay law — are the chapter's most frequently repeated question format.
Is binding energy per nucleon tested conceptually?
Yes — understanding why the binding-energy-per-nucleon curve explains both fission (heavy nuclei) and fusion (light nuclei) releasing energy is a recurring conceptual question.
