Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 2/5
How did the later discovery of noble gases affect Mendeleev's periodic table?
- A. It required the complete rejection of periodic classification
- B. It forced noble gases into the alkali-metal group
- C. It required all elements to be reordered alphabetically
- D. Noble gases could be placed in a separate group without disturbing the existing arrangement
Example 3 · difficulty 3/5
Mendeleev placed tellurium before iodine even though their atomic-mass order appeared to suggest the reverse. What best explains this decision?
- A. He gave greater importance to chemical similarity, placing iodine with the halogens
- B. He already knew that iodine had a smaller atomic number than tellurium
- C. He treated tellurium and iodine as isotopes of one element
- D. He arranged this part of the table according to alphabetical order
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 2022 Chemistry Periodic Properties 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 2022 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.
