NEET 2022 Chemistry Periodic Properties Questions
Use this page to connect the official 2022 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
periodic trends, effective nuclear charge and anomalous behaviour.
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

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.
