Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 1/5

Which statement correctly expresses Newlands' Law of Octaves?

  • A. When elements are arranged by increasing atomic mass, every eighth element has properties similar to the first
  • B. Every group must contain exactly eight elements
  • C. Atomic masses repeat after every eight elements
  • D. Only eight chemically distinct elements can exist

Example 2 · difficulty 1/5

Why did Newlands use the word “octaves” for his classification?

  • A. He identified eight isotopes of every element
  • B. He compared the recurrence of elemental properties with the similarity of the eighth musical note to the first
  • C. He divided all elements into eight equal mass ranges
  • D. He believed that each atom contained eight particles

Example 3 · difficulty 1/5

Up to which element did Newlands' Law of Octaves appear to work satisfactorily?

  • A. Sodium
  • B. Chlorine
  • C. Calcium
  • D. Iron

Frequently asked questions

Are these official NEET 2020 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 2020 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.
