### dsp3 vs sp3d

What's the difference between writing hybridization with the d before sp vs the d after sp? I know both of them mean basically the same thing, but can someone explain to me why Dr. Lavelle chooses to write it so that d comes before sp?

Similar to how we write electron configurations, the d goes first if it is in a prior shell. Even though we fill the d subshell after we fill the s and p subshells from the previous shell, we write the d first.

According to Lavelle, it doesn't really matter IIRC.

I think they are the same. Just depends on personal preferences.

He said he chose to write it that way so he'd remember to tell us that the order doesn't matter.
