AIIMS 2019 Chemistry Quantum Numbers MCQ Question

Type: MCQ-conceptual-Medium-Class 11

For 4p electron, n=4,l=1,m=1,0,+1n = 4, l = 1, m = -1, 0, +1 and s=+1/2s = +1/2 or 1/2-1/2

Correct Answer

Option C

Detailed Explanation

In the context of electron configuration, the 4p subshell can accommodate a total of six electrons, with the quantum numbers n=4n = 4 (principal), l=1l = 1 (azimuthal), and m=1,0,+1m = -1, 0, +1 (magnetic) representing the three possible orientations of the p orbital. The spin quantum number ss can be either +12+\frac{1}{2} or 12-\frac{1}{2}, allowing for two electrons per orbital. Since option C correctly identifies the possible configurations for a 4p electron, it is valid, while the other options are not applicable as they do not provide relevant information regarding the electron's quantum state.
