Anti protons are made from anti up anti up anti down quarks, Anti neutons are made from anti up anti down anti down. The proton is made from uud quarks (charge +2/3 +2/3 -1/3 = 1), and the neutron is made from udd quarks (charge +2/3 -1/3 -1/3 = 0). To explain this, they were given a property known as strangeness, which is exhibited by strange quarks (strangeness -1) and anti strange quarks (strangeness +1).īaryons are made up of three quarks. When Kaons decayed, scientists observed that the particle took longer to decay than predicted, meaning that the particle decayed under weak interactions. There are: up, down, strange, anti up, anti down and anti strange quarks. Quarks are the particles that make up Hadrons. Twelve of these are the force carrying particles- the photon, the weak force carriers W-, W+, Z0, and the eight gluons. There are 36 confirmed fundamental particles, including anti-particles, according to Professor Craig Savage from the Australian National University. These include: electrons, muons, electron neutrino, muon neutrino, and their respective antiparticles. There are two types of subatomic particles: elementary and composite particles. Leptons are fundamental particles and so can not be split into any smaller particles. − Leptons are particles that interact using the weak nuclear force. Pions and kaons can be positive, neutral and negative.īaryons and mesons aren't fundamental particles and so can be split into smaller particles known as quarks. Mesons are hadrons that do not decay into protons, such as: pions and kaons. These include: protons, neutrons, antiprotons and antineutrons.
Hadrons come in two further groups, Baryons and Mesons.īaryons are hadrons that can decay into or are protons. − Hadrons are particles that interact using the strong nuclear force. However there are many more subatomic particles than this that can be divided into two groups, Hadrons and Leptons. Fundamental particles like proton and neutron located on the positive charge nucleus, electron are the extranuclear subatomic part of an atom carries the negative charge. These three particles are the fundamental part of an atom of the periodic table chemical elements. antiparticle chion electron graviton lepton antilepton meson. Elementary particles or subatomic particles like electrons, protons, and neutrons in physics or chemistry were discovered by Scientists Thomson, Golstine, and Chanweak. At GCSE you would have learned about the subatomic particles known as protons and neutrons and electrons. Subatomic particles are the building blocks of matter and energetic reactions within matter.
