Q1: 2D1/2 will split into ______ components in magnetic field.

A. None of these
B. 8
C. 6
D. 4

Explanation

The splitting in a magnetic field is determined by the formula $2j + 1$ , where $j$ is the total angular momentum quantum number.

For $2D_{1/2}$ , $j = 1/2$ , so the number of components is $2 (1 / 2) + 1 = 6.$
