charge isn't the only properties that are different in particles and antiparticles.

what else is there? Im new to this type of thing

spin

opposite directional spin on the particles or on the atoms? how would that affect the reaction?

spin isn't really the rotation of the particle just like quarks colors aren't red, blue, ect.

lol, true, but what spins? does the particle spin within the atom, or does the atom spin itself? and how does this affect the reaction between the matter and the anti-matter?

here is a link that describes what i am talking about

AHHH, ok; that clarifies a lot. Thanks

But wouldn't it have to be opposite in value to be anti, like spin up vs. spin down? Isn't that how protons and neutrons couple? I am really just looking at how electrons act, but they only are described to have spin because they have magnetic moment and that is described as a charge that is in motion. Or am I way off?

Protons and neutrons couple by the strong nuclear force. There is an energy dependence of nucleons on spin, but that is at least in part a consequence of the Pauli exclusion principle (e.g. in Tritium, the neutrons would have to have anti-aligned spins to be in the same energy level)

Well, we don't really know 100% sure that the particles don't rotate around. Actually, doesn't the spin actually suggest that they are rotating?

No. I think the value for the angular momentum (Planck's constant) suggests superluminal speeds for some particles if there was physical rotation involved. Spin is just intrinsic angular momentum.
