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.
