RE-NEET 2024 Chemistry Quantum Numbers MCQ Question
Type: MCQ-numerical-Hard-Class 11
The quantum numbers of four electrons are given below:
I. n = 4; l = 2; m₁ = -2; s = -½ II. n = 3; l = 2; m₁ = 1; s = +½ III. n = 4; l = 1; m₁ = 0; s = +½ IV. n = 3; l = 1; m₁ = -1; s = +½
The correct decreasing order of energy of these electrons is
A
IV > I > III > I
B
I > III > II > IV
C
III > I > II > IV
D
I > II > III > IV
Correct Answer
Option 2
Detailed Explanation
Energy levels are determined by the principal quantum number n and azimuthal quantum number l. Higher n and l values indicate higher energy.
