Spin states

[Brandon Yu]

How do spin states work conceptually in each type of orbital?

[Kevin Zhang 3K]

Imagine an electron going along the sphere of the s orbital. Another electron will be moving the opposite direction of the first electron. One would be spinning up/counter clock wise, and the other would be spinning down/ clock wise.

[Vicky Tong 3E]

Hi! I would reference Hund's rule where all orbitals need to be filled with one electron spinning up (+1/2). Afterwards, you would pair another electron spinning down (-1/2), therefore you would have two electrons in each orbital with opposite spins.

Each orbital can only have 2 electrons, and, firstly, each orbital is filled once with an electron with the same "parallel" spin. Once each orbital in the subshell has one electron, each is then filled fully with another electron of an opposite spin. In the same orbital, these second electrons have to have an opposite spin as the first. I understood spin as simply a property of electrons, which like other electron properties like orientation and quantum number ml, have a specific quantum number (ms).
