### Lone pair

Should we consider lone pair as sigma or pi bond when we do hybridization?
For example if an central atom is linked with 3 atoms (sigma bond) and 1lone pair is it s1p3 or s1p2 hybridization?

Thank you very much!

I believe that the hybridization would be s1p3 because of the four regions of electron density

I think hybridization depends on the number of regions of electron density, not the sigma or pi bonds, so it would be sp3

### Re: Lone pair

it is solely dependent on the number of electron densities so we would consider all bonds (single, double, triple) and lone pairs as 1 region of electron density. therefore the hybridization would be sp3.

hybridzation depends on the number of regions of electron density. since there is 4 regions (1 lone pair and 3 atoms) the hybridization would be s1p3.
