Original practice preview

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

Example 1 · difficulty 2/5

Why does atomic number provide an unambiguous identity and sequence for elements in the modern periodic table?

A. It is always numerically equal to the relative atomic mass
B. It changes when an atom forms an ion
C. It equals the number of protons and has a unique whole-number value for each element
D. It is identical for all elements in one group

Example 2 · difficulty 2/5

An element has the ground-state electronic configuration [Ne] 3s² 3p⁵. What is its position in the long form periodic table?

A. Period 2, group 17, p-block
B. Period 3, group 15, p-block
C. Period 4, group 17, p-block
D. Period 3, group 17, p-block

Example 3 · difficulty 1/5

Which placement corresponds to an element with electronic configuration [Ar] 4s¹?

A. Period 4, group 1, s-block
B. Period 4, group 11, d-block
C. Period 3, group 1, s-block
D. Period 4, group 2, s-block

Frequently asked questions

Are these official NEET 2026 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 2026 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.
