Document Summary

At one point we thought that particles could not be subdivided beyond the electron, the proton and the neutron. All fundamental or elementary particles are either bosons or fermions, depending on their spin. Theorized that every force is an exchange of particles! Weak interaction - hadrons & leptons - z & w particles. Strong interactions - holds together quarks - ex of gluons. Chemicals & elements have different nuclear masses, but since the number of. Protons is fixed, this extra mass is made up of neutrons: these differently weighted versions of the same chemical are called isotopes, luckily, we"ve devised notation to keep track of all this . A = atomic mass #, baryon #, z + n = a. Ex: in the case of carbon, this has many stable isotopes: How many electrons are there: 238, 92, 146. # of protons = # of electrons in a stable atom. There are: 100 elements, 300 stable isotopes of those elements.
