Match List I with List II List-I (Element) A. N B. S C. Br D. Kr List-II (Electronic Configuration) I. [Ar] 3d^10 4s^2 4p^5 II. [Ne] 3s^2 3p^4 III. [He] 2s^2 2p^3 IV. [Ar] 3d^10 4s^2 4p^6 Choose the correct answer from the options given below:
- A-IV, B-III, C-II, D-I
- A-I, B-IV, C-III, D-II
- A-III, B-II, C-I, D-IV
- A-II, B-I, C-IV, D-III
Correct answer: A-I, B-IV, C-III, D-II
Solution
The correct option matches each element with its respective electronic configuration: Nitrogen (N) has the configuration [He] 2s^2 2p^3, Sulfur (S) is [Ne] 3s^2 3p^4, Bromine (Br) is [Ar] 3d^10 4s^2 4p^5, and Krypton (Kr) is [Ar] 3d^10 4s^2 4p^6, accurately reflecting their positions in the periodic table.
