5.3.2 FUNDAMENTAL PARTICLES

HideShow resource information
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
