hybridization of lone pairs

Ok so for lone pairs, do we just look at the regions of electron density and determine they hybridization for just that atom? For example, if I was given a N with 3 regions of electron density (one region being composed of a lone pair), would I write N= 2sp2?

Re: hybridization of lone pairs

Yes, hybridization is solely based on regions of electron density. An atom with two bonds and one lone pair would have the same hybridization (sp^2) as something with three bonds and no lone pair.

Yes, to find the hybridization just count the number of regions of electron density, this includes lone pairs on the central atom and don't forget that double bonds and triple bonds bonded to the central atom still count as one region of electron density.

Re: hybridization of lone pairs

We mainly look at regions of electron density rather than bonding or lone pairs, in case of hybridization.
