Sz is the z-component of spin angular momentum and ms is the spin projection quantum number. For electrons, s can only be 1/2, and ms can be either +1/2 or –1/2. Spin projection ms = +1/2 is referred to as spin up, whereas ms = −1/2 is called spin down.
How do you find total spin quantum number?
Let us call the initial particle particle a, the spin ½ particle particle b, and the spin 0 particle particle c. Then the total spin of the two particles in the final state is S = Sb + Sc = Sb. Therefore the spin quantum number is s = ½.
How many spin states are possible for the spin quantum number?
two There are two allowed spin states, up and down.
How do you know if the spin quantum number is positive or negative?
0:0610:05Spin quantum number: ms Chem161 (7.6) – YouTubeYouTubeStart of suggested clipEnd of suggested clipNumber doesn't depend on anything it only has the possible values of plus 1/2 or negative 1/2. AndMoreNumber doesn't depend on anything it only has the possible values of plus 1/2 or negative 1/2. And these correspond to what we call spin up versus spin down.
How do you calculate spin?
Identifying Spin Direction
- Determine the number of electrons the atom has.
- Draw the electron configuration for the atom. See Electronic Configurations for more information.
- Distribute the electrons, using up and down arrows to represent the electron spin direction.

What does spin 3 2 mean?
This operator can be along any direction but the eigenvalue will always be for any of the spin state operators along any direction with respect to a specified coordinate axis. In other words, a spin of 3/2 refers to a particular state of the system irrespective of any orientation.
How many spin are possible for an electrons?
two The electron can spin in two directions: The spin up and spin down direction are corresponding to the spinning in the +z or –z direction.
Which quantum numbers can be negative?
The Magnetic Quantum Number (ml) Given a certain l, ml is an interval ranging from –l to +l, so it can be zero, a negative integer, or a positive integer.
