JEE Main 2026 — 28 January, Evening Shift — Question 52

Consider the elements N,P,O,S,Cl\mathrm{N}, \mathrm{P}, \mathrm{O}, \mathrm{S}, \mathrm{Cl} and F . The number of valence electrons present in the elements with most and least metallic character from the above list is respectively.

  1. Option A:

    7 and 5

  2. Option B:

    5 and 6

  3. Option C:

    5 and 7

    Correct
  4. Option D:

    6 and 7

Answer: C

Step-by-step solution

Metallic character increases down a group and decreases across a period.

Among the given elements, P is the most metallic since it is below N in group 15. P has 5 valence electrons.

F is the least metallic since it is the most electronegative element. F has 7 valence electrons.

Thus required numbers are 5 and 7.
