### Lone Pairs

I know that when we have lone pairs the 3-D shape changes, however does Hybridization change as well due to have lone pairs instead of bonds?

I think the shape in general will stay the same just because of the areas of electron density, however the exact structure will not be identical. For example, the difference between a trigonal pyramidal and tetrahedral structure is the replacement of one lone pair of electrons with a bond. The bond angles between the other atoms not including the variable lone pair very similar.

I believe hybridization takes into account the lone pairs of a molecule. It is further explained on this document; http://www.chem.ucla.edu/~harding/notes ... als_01.pdf

I think hybridization changes if the lone pairs are attached to the central atom, but that's it.

Does that mean if the atom has 3 lone pairs and one bond, its hybridization would be sp^3?

### Re: Lone Pairs

I believe so because there are 4 areas of electron density
