Has 3 generationsa and only formed in hadrons 1 of 11 lepton First gen leptons.electron +1, Neutrinos have +1,positron and anti-neutrino -1. 2 of 11 Proton Baryon composed of uud . This gives charge of +1 and baryon no. +1 3 of 11 Neutron Baryone composed of udd.This has a charge of 0 and baryon no. +1 4 of 11 Electron Has little mass and carries negative charge of -1. has lepton no.+1. 5 of 11 positron same as electron but has charge of +1 and has lepton no. -1. 6 of 11 Hadron Contains 3 quarks and contains either a mix of quarks and anti-quark.Have strong force. 7 of 11 Baryon Name given to particles which consist of 3 quarks. An anti-baryon contains 3 anti-quarks 8 of 11 Meson This particle contain 2 quarks one quark, one anti-quark. 9 of 11 pion Mesons are unstable, decaying into leptons and photons . 10 of 11 Neutrino carries no charge and has lepton no. +1 and anti = -1 11 of 11
