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 1 · difficulty 2/5

Which feature of Newlands' arrangement directly illustrates the forced placement of elements in his scheme?

  • A. He left systematic gaps for elements that had not yet been discovered
  • B. He placed all noble gases between the halogens and alkali metals
  • C. He ordered iodine before tellurium using atomic numbers
  • D. He placed cobalt and nickel in the same slot and associated them with the column containing fluorine, chlorine and bromine

Example 2 · difficulty 1/5

Which statement is Mendeleev's periodic law?

  • A. The properties of elements are periodic functions of their atomic masses
  • B. The properties of elements depend only on their physical states
  • C. The atomic numbers of elements recur periodically
  • D. Every eighth element has exactly the same properties

Example 3 · difficulty 2/5

Which pair of considerations primarily guided Mendeleev while arranging elements in his periodic table?

  • A. Alphabetical order and year of discovery
  • B. Increasing atomic mass and similarity in chemical properties
  • C. Density and physical state alone
  • D. Atomic number and neutron number

The evidence-first practice loop

  1. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2021 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 2021 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.
