Are there different types of subatomic particles?

At the subatomic level are all molecules exactly alike or do they have differences? Would the molecules from a persons brain be the same as a tiny molecule from a leaf or car door?

    Regular ol' matter contains three (main) fundamental particles:

    Up quarks, down quarks, and electrons.

    The up and down quarks are collected into groups of three:

    Up, up, down makes a proton with charge +1.

    Up, down, down makes a neutron with charge 0.

    An electron has charge -1.

    Protons and neutrons form the nuclei of elements and are held together by a colour charge (mediated by gluons), electrons congregate in energy levels around the nuclei.

    Your brain, a leaf, nuclear waste, it's all the same stuff. The full picture is a lot more complicated though, and there are many, many other particles though than just these.

    There are six quarks and six anti-quarks, six leptons (the class to which electrons belong to) and six anti-leptons, there are four bosons (these are force mediators) one of which is the photon, there may be more bosons, one is hypothesised to be the Higgs boson. Together these particles comprise the class known as fermions.

    Then all sorts of other particles arise from combinations of these particles, protons and neutrons for example are part of the baryon. There are also mesons which contain a quark and anti-quark. Both mesons and baryons are classed as hadrons.

    There are different subatomic particles. As far as your second question, there are similar particles in similar atoms that make up similar molecules. These things become different when you mix different subatomic particles together.
