NEET 2023 Chemistry D- and F-Block Elements Questions
Use this page to connect the official 2023 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 2/5
What is the main electronic reason that transition elements commonly show variable oxidation states?
- A. Only inner-shell p electrons participate in their bonding
- B. Their d subshells are always completely filled
- C. The ns and (n−1)d electrons have comparable energies and can both participate in bonding
- D. Their ns electrons are too tightly bound to be removed
Example 3 · difficulty 3/5
Which statement correctly relates the common oxidation states of scandium and zinc to stable d configurations?
- A. Sc²⁺ is [Ar] 3d⁰, while Zn²⁺ is [Ar] 3d⁹
- B. Sc³⁺ is [Ar] 3d¹, while Zn²⁺ is [Ar] 3d⁹
- C. Sc⁺ is [Ar] 3d⁰, while Zn³⁺ is [Ar] 3d¹⁰
- D. Sc³⁺ is [Ar] 3d⁰, while Zn²⁺ is [Ar] 3d¹⁰
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 2023 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 2023 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.
