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

Chlorine has a more negative electron gain enthalpy (−349 kJ mol⁻¹) than fluorine (−328 kJ mol⁻¹), which is an exception to the expected group trend. This is because:

A. chlorine has a higher nuclear charge than fluorine
B. fluorine already possesses a stable octet, so it does not accept electrons
C. the added electron in fluorine enters the larger 3p subshell
D. the very small size of fluorine causes strong interelectronic repulsions in its compact 2p subshell

Example 2 · difficulty 3/5

The first four ionization enthalpies of an element are 496, 4562, 6910 and 9543 kJ mol⁻¹ respectively. To which group of the modern periodic table does the element belong?

A. Group 13
B. Group 2
C. Group 1
D. Group 16

Example 3 · difficulty 2/5

An element has atomic number 33. Its position in the long form of the periodic table is:

A. Period 4, Group 15, p-block
B. Period 4, Group 13, p-block
C. Period 3, Group 15, p-block
D. Period 4, Group 15, d-block

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 2017 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 2017 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.
