Structure of Atom — NEET/JEE Questions, Notes & Weightage
Class 11 Basic Concepts & Atomic Structure NEET weightage: High 1,304 questions
Covers atomic models (Thomson, Rutherford, Bohr), quantum numbers, electronic configuration rules (Aufbau, Pauli, Hund), and de Broglie/Heisenberg's principles. Electronic configuration and quantum-number questions are a dependable, almost formulaic source of marks.

Frequently asked questions
What is the most reliable question type here?
Writing or verifying electronic configurations (including exceptions like Cr, Cu) and identifying valid sets of quantum numbers are the most consistently repeated formats.
Is Heisenberg's uncertainty principle tested numerically?
Occasionally — simple uncertainty-in-position/momentum calculations appear, but conceptual questions (what the principle implies) are more common than numericals.
