JEE Main 2026 · 28 January · Evening Shift · Chemistry · Classification of Elements and Periodicity in Properties
Consider the elements N, P, O, S, Cl and F. The number of valence...
Consider the elements and F. The number of valence electrons present in the elements with most and least metallic character from the above list is respectively.
Options
- A7 and 5
- B5 and 7
- C5 and 6
- D6 and 7
Correct answer
B. 5 and 7
Step-by-step solution
Valence electrons: N(5), P(5), O(6), S(6), Cl(7), F(7).
Metallic character order in the list: P > S > N > Cl > O > F.
Most metallic character: P with 5 valence electrons.
Least metallic character (most nonmetallic): F with 7 valence electrons.
F is the most electronegative and has the smallest atomic size, making it most nonmetallic.
Metallic character order in the list: P > S > N > Cl > O > F.
Most metallic character: P with 5 valence electrons.
Least metallic character (most nonmetallic): F with 7 valence electrons.
F is the most electronegative and has the smallest atomic size, making it most nonmetallic.
