Frequently asked questions

What makes a d and f-Block Elements question "important" for JEE?

Important questions test core concepts that appear frequently across JEE Main and Advanced papers — definitions, standard formulas, and classic problem types.

Which subtopics in d and f-Block Elements are high-weightage?

Key areas include Transition Elements: General introduction, electronic configuration, occurrence and characteristics, General trends in properties of the first-row transition elements: physical properties, ionization enthalpy, oxidation states, atomic radii, colour, catalytic behaviour, magnetic properties, complex formation, interstitial compounds, alloy formation, Preparation, properties and uses of K2Cr2O7 and KMnO4, Inner Transition Elements, and more. Prioritise these before moving to edge cases.

How many important questions should I revise?

Revise 30–50 important MCQs per unit in the last month before JEE. Focus on questions you got wrong at least once.
