Question

What angles can the spin (s) of an electron make with the zaxis?

a) 0 degrees
b) 45 degrees
c) 90 degrees
d) 180 degrees

Answer 1

The spin (s) of an electron can make two angles with the z-axis: 0 degrees and 180 degrees, representing the spin up and spin down states, respectively.

Step-by-step explanation:

The spin (s) of an electron can make two angles with the z-axis: 0 degrees and 180 degrees. These angles represent the two possible spin states of an electron: spin up (+1/2) and spin down (-1/2) along the z-axis. In the spin up state, the electron's spin is aligned with the positive direction of the z-axis (0 degrees).

In the spin down state, the electron's spin is aligned with the negative direction of the z-axis (180 degrees).
