### what are terminal atoms?

I read from the textbook that terminal atoms are not regarded as hybridized. (i.e. the Cl molecules in PCl5) What are the definition of terminal atoms? Thank you!

It is any atom besides the central atom. So pretty much everything connected/surrounding the central atom.

Actually, the Cl would have the hybridization of sp3.

Yeah, the central atom's valence shell has been hybridized in order to accommodate the electrons needed for a stable structure. The terminal atoms simply provided the electrons needed by the central atom.
