"which" here refers to "all known subatomic particles". "all known subatomic particles" is plural so "some of which" becomes "some of all known subatomic particles".

In the first part, there are two objects: "this model", which is singular, and "all known subatomic particles", which is plural. Hence, "them" in the second part must refer to "all known subatomic particles".
