(A)\(1 \mathrm{~s} \lt 2 \mathrm{p} \lt 3 \mathrm{~d} \lt 4 \mathrm{~s}\)
(B) \(1 \mathrm{~s} \lt 2 \mathrm{~s}=2 \mathrm{p} \lt 3 \mathrm{~s}=3 \mathrm{p}\)
(C) \(1 \mathrm{~s} \lt 2 \mathrm{~s} \lt 2 \mathrm{p} \lt 3 \mathrm{~s} \lt 3 \mathrm{p}\)
(D) \(1 \mathrm{~s} \lt 2 \mathrm{~s} \lt 4 \mathrm{~s} \lt 3 \mathrm{~d}\)
Choose the correct answer from the options given below :
- A (A) and (C) only
- B (B) and (D) only
- C (C) and (D) only
- D (A) and (B) only
Answer & Solution
Correct Answer
(C) (C) and (D) only
Step-by-step Solution
Detailed explanation
For single electron species energy only depends on ' n ' (principal quantum number) So energy of \(2 \mathrm{~s}=2 \mathrm{p}\) and energy of \(3 \mathrm{~d} < 4 \mathrm{~s}\)
