Chemistry - d and f Block Elements

Practise 13 NEST (NISER) previous year questions on d and f Block Elements, compiled from papers spanning 2011 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty NEST (NISER) tests.

d and f Block Elements has been asked in 9 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 13 questions in all. 8% of them were easy, 77% moderate and 15% tough. Most of its questions came from 2024, with 3 questions that year. In the last three years (2024–2026) it had 6 questions across 4 papers, about 1.5 per paper.

The chapter's 3 topics are not weighted equally: Properties of D-block elements (7 questions, 54%), Compounds of Transition Metals (4 questions, 31%), and F-Block elements (2 questions, 15%) have been asked the most. Properties of D-block elements has also led over the last five years, with 3 questions. Properties of D-block elements has produced the most tough questions (1).
