PhysicsParticle physicsA2/A-levelOCR Created by: upsidedown1004Created on: 26-06-16 16:12 Why are protons and neutrons not fundamental particles? as they contain charged constituents called quarks 1 of 11 Name the types of quark up down top bottom stage charm 2 of 11 Sate the charge, baryon number and strangeness of each of the quarks ... 3 of 11 What is a hadron? explain the types of hadrons collection of quarks affected by strong nuclear force/ baryons - 3 quarks/ mesons quark and antiquark 4 of 11 What is the quark arrangement in a neutron? udd 5 of 11 What is the quark arrangement in a proton? uud (remain Positive you'll just go up and up and up) 6 of 11 describe the quark model of beta minus decay weak interaction between quarks/ up is able to turn into a down and turns a neutron into a proton by emitting an electron 7 of 11 Describe Baryons hadron/ neutrons and protons/ always decay into protons/ neutrons less stable/ baryon number always stays the same 8 of 11 Describe mesons unstable/ small/ quark and anti/ pions and kaons 9 of 11 Describe the quark model of beat plus decay proton -> neutron positron and neutrino / uud -> udd + e+ + ve 10 of 11 What are leptons? not affect day strong nuclear force/ electrons and neutrinos/ all decay into electrons/ almost 0 mass 11 of 11
