History of the Atom

So this year I didn’t take AP Chem, but rather a college chem class, so we didn’t really talk about the origins and the experiments that lead to the discovery of certain parts of the atom. However, in my Barrons book, they talk about the history of the atom. Is it worth looking over? I don’t really see how it is relevant to doing chemistry.

This is for the SAT Chem test, btw. If you know anything referring to the AP test as well, that’d be helpful, too.
