I forgot about the gluons! We musn't forget them! They are a bit more complicated. For these puppies you can't just picture them as the billiard balls we see electrons and quarks as. Gluons are more like photons, while they are a particle, they also carry stuff...that is, photons carry enegry and deposit it and stuff...but gluons are the 'force carrier' for the strong interaction. They don't have any mass or charge, and there are 8 types.
Ok...now for the hadrons. Hadrons are just stuff made of quarks. there are a few different types of hadrons. We have measons, made of a quark and an anitquark, and baryons, made of three quarks (protons and neutrons are baryons). And that's it for the figure from yesterday.
Other particles you may or may not have heard of include the neutraino, and the muon and the ever popular higgs boson. The muon is just another kind of lepton, like the electon, exept heavier. The neutrino is just one 'flavor' of the leptons. We have an electron nuetrino a muon nuetrino and a tauon (the 3rd lepton) nuetrino and thier antiparticles. The higgs boson is another type of 'force carrier' partile that is suppose to give mass to things. It has yet to be observed (this is the job of most of the large hadron collider), but it is needed theoretically for our whole model to work.
Here is a link to the particle zoo, a very humorous look at the standard model and I've included a picture (you'll have to click on it) with a plethora of information on the stranded model and a great picture of how atoms are really composed.
