How did they determine that the minimum oxidation number for chlorine was -1?

The oxidation number is determined by the electrons that would be added/lost to form a noble-gas configuration. Because Cl has 7 e-, it would add one electron to get to the electron configuration of Argon. Because it adds one electron, it would have an oxidation number of -1.
