### Are terminal atoms hybridized?

Are terminal atoms hybridized? When can we tell if they are?

For instance, in 2.45, the O double-bonded to the central C atom has sp2 hybridization. How about in the case of CS2 in 2.59(b), would the S atoms be hybridized to sp2 as well? How about terminal atoms that are halogens?

### Re: Are terminal atoms hybridized?

Each atom is hybridized based on the number of electron domains it has.

In the case of CS2, the S atoms have 1 double bond with C and 2 lone pairs, so it would also have 3 electron domains and yes it would be hybridized to sp2 as well.
As for terminal atoms that are halogens, it just depends again on counting the number of electron domains the atoms have.
