NEET 2018 Chemistry D- and F-Block Elements Questions
Use this page to connect the official 2018 paper with current Chemistry practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
electronic configurations, oxidation states, colour, magnetism and lanthanoid trends.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 4/5
Actinoids exhibit a much wider range of oxidation states than lanthanoids because:
- A. 4f orbitals are more deeply buried than 5f orbitals
- B. the actinoid contraction is stronger than the lanthanoid contraction
- C. the 5f, 6d and 7s subshells have comparable energies, so electrons from all three can take part in bonding
- D. actinoids possess a completely filled 5f subshell
Example 3 · difficulty 1/5
Where is the d-block located in the long form of the periodic table?
- A. In groups 3–12, between the s-block and p-block, beginning in period 4
- B. In groups 1–2, at the left of the table, beginning in period 1
- C. In groups 13–18, at the right of the table, beginning in period 2
- D. In the two rows placed separately below the main table, beginning in period 6
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2018 Chemistry D- and F-Block Elements PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2018 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
