The Standard Model 1 Flashcards
(21 cards)
What are atoms made up of
Protons , neutrons , electrons
What are protons and neutrons made up of
Quarks
What is a particle that makes up matter
A fermion
What are quarks
Quarks are fundamental or elementary particles this means they are not made up of anything smaller
What are the 6 types of quarks
- up
- down
- strange
- charm
- top
- bottom
What are leptons
They are fundamental particles. For example an electron is a lepton and some other leptons are muon and tau
What are composite particles
Composite particles are made up of more than 1 quark
What is any particle made of more than 1 quark called
A hadron
What are the 2 main types of hadrons
- baryons
- hadrons
How many quarks are baryons made up of
3 quarks
How many quarks are hadrons made up of
2 quarks (usually made of 1 quark and1 anti-quark)
What is an anti particle
The anti particle has the same mass but opposite charge and every particle has an anti matter equivalent
What are the 4 fundamental forces
- gravity
- electronegativity
- strong nuclear force
- weal nuclear force
What is a force mediating particles
Bosons and each fun do entail force has its own boson
What is the boson for electromagnetic
Photon
What is the boson for gravity
Graviton
What is the boson for strong nuclear force
Gluon
What is the boson for weak nucleus force
W+ , W- , Z bosons
What happens during beta decay
- during beta decay, a neutron turn into a proton and a electron and the electron is ejected from the nucleus of the decaying atom
What does beta decay provide evidence for
Anti neutrino
What is beta decay a product of
Weak force
