I have seen that lone pairs are almost invariably counted for determining the hybridisation of an atom.

My question is why can't they remain in unhybridised orbitals.

    $\begingroup$ @ringo Related yes, duplicate no. Also I find the answers given there highly unsatisfactory. $\endgroup$ Commented Mar 7, 2016 at 7:41

    $\begingroup$ There are many examples of lone pairs in orbitals that are unhybridized. See this earlier answer for several examples. Another example, phosphine is discussed here. $\endgroup$
