How many elementary particles have been discovered.
Norman said:please see http://pdg.lbl.gov/pdg.html
There are 6 different quarks, 6 different leptons, and 12 different gauge bosons. Then you have all the antiparticles for these different particles. This is in regards to the standard model of particle physics. Please see the link above for much more detail.
Cheers,

It seems that for fermions it is a question of mass, if the mass is the same you consider it to be the same particle, even if the charge is not. But for bosons we count W+ and W- as two particles.
If we include charge and antiparticles in the fermions, we have
6*3*2= 36 quarks and
6*2= 12 leptons
If we consider Parity, we have
36*2= 72 quarks
12*2= 24 leptons, or we had 18 if there were not right neutrinos.
thus about 96 "particles".
As of now, scientists have discovered a total of 17 elementary particles.
Elementary particles have properties such as mass, spin, charge, and flavor. These properties determine their interactions and behavior.
No, the term "elementary" implies that these particles are indivisible and cannot be broken down into smaller components.
Elementary particles are classified into two categories based on their spin - fermions and bosons. Fermions have half-integer spin while bosons have integer spin.
Elementary particles play a crucial role in our understanding of the universe and the fundamental laws of physics. They are the building blocks of matter and their interactions govern all physical phenomena.
