Classification of Elements and Periodicity in Properties — NEET/JEE Questions, Notes & Weightage
Class 11 Basic Concepts & Atomic Structure NEET weightage: Medium 529 questions
Covers the modern periodic law, periodic trends (atomic radius, ionization enthalpy, electron gain enthalpy, electronegativity), and anomalous trends. Trend-comparison questions (which element has the higher/lower value, and why) are this chapter's dominant NEET/JEE format.

Frequently asked questions
What trend gets asked about most?
Ionization enthalpy trends and their exceptions (e.g. why Be > B, or N > O) are the most frequently tested periodic-trend anomalies.
Are diagonal relationships and anomalous pairs tested?
Yes, at a basic level — Li/Mg and Be/Al diagonal relationships occasionally appear as factual recall questions.
