Sub Atomic particles
Properties of the Three Basic Sub-Atomic Particles
|Particle||Electric Charge (C)||Atomic Charge||Mass(g)||Atomic Mass (Au)||Spin|
|Protons||+1.6022 x 10-19||+1||1.6726 x 10-24||1.0073||1/2|
|Neutrons||0||0||1.6740 x 10-24||1.0078||1/2|
|Electrons||-1.6022 x 10-19||-1||9.1094 x 10-28||.00054858||1/2|
Standard Model's Elementary particle include followings
1) Six "flavors" of quarks which are as follows: bottom, top, strange, and charm, up, down.
2) Six types of leptons which are as follows : electron, electron neutrino, muon, neutrino, muon , tau neutrino, tau.
3) (force carriers) Twelve gauge bosons the photon of electromagnetism, the three W and Z bosons of the weak force, and the eight gluons of the strong force.
Example of composite particles -Two up quarks and one down quark make up a proton , While two protons and two neutrons make up the atomic nucleus of helium-4 . All hadrons are included in composite particles, a group composed of baryons (protons and neutrons are included as baryons) and mesons (pions and kaons are the examples of it ) all are examples of composite particles.
