Drawing the configuration

Postby Deap Bhandal L1 S1J » Thu Nov 02, 2017 1:05 pm

When filling up orbitals does it matter if you start with spin downs or spin ups?

Nope it does not matter, although you have to be consistent. For example, if you start filling spin-ups in the 2px orbital, you have to continue filling spin-ups in the 2py and 2pz orbitals until you need to pair all the spins in the p-orbitals to complete the configuration.

According to Hund's Rule, electrons in the same subshell occupy different orbitals with parallel spin, but when electrons are initially added, it doesn't matter whether the spin is up or down, as long as they are all parallel.

So technically we don't know if a certain electron has positive or negative spin?

I don't think so. Unless you are given ms= 1/2 or ms= -1/2 then you know it's spin up or spin down.
