Electron Spin

Postby Victoria Luu - 1C » Wed Oct 24, 2018 7:37 pm

How do you determine the electron spin? Is it based off the Aufbau Diagram?

I do not think we are required to know whether an electron spin is up or down. I think the only thing to note here is that if two electrons are paired, they have opposite spin. If two electrons are parallel, on the other hand, they have the same spin.

I believe for the ground state electron configuration of an atom, the convention is to fill orbitals with +1/2 spin and then go back to pair electrons with a -1/2 spin.

A +1/2 is a spin up, and a -1/2 is a spin down. I don't know to what extent we will use this, but when you are filling an Aufbau diagram, make sure to follow to Pauli Exclusion Principle and Hund's Rule. When filling it out the diagram, start with any spin, I do not think it matters. Electrons want to be stable, so every orbital in a subshell is singly occupied with one electron before they have to fill up the next subshell. They have to have different spins.
Hope this helps!
