### Forming the hybridization

When naming the hybridization of an atom, why do you put the superscript only after the p, for example, bromine is sp^3d, even though d has two electrons?

### Re: Forming the hybridization

We do not just put the superscript after the p. We sometimes put it after the d too. It depends on the atom itself. In SF6, the S atom forms hybrid orbitals of sp3d2. The amount of orbitals used in the structure responds to the hybridization. Since we used 6 orbitals, we have to go to s (1 orbital), p (3 orbitals) and d (2 orbitals). We can only use d orbitals when we're doing valence shell expansion.
