Particle Physics
- What is the purpose of decay?
- In order to make the
atom/element more
stable
- In order to make the
atom/element more
stable
- A Feynman diagram shows
the existence of particles
through time
- How do the values for mass number and
atomic number change when a beta-
particle is emitted?
- The mass number stays
the same and the
atomic number
increases by 1
- The mass number stays
the same and the
atomic number
increases by 1
- A photon is a 'packet of energy' or a light
particle. All electro-magnetic waves can be
photons
- What are the 2 'families' of particles
and what are the
similarities/differences?
- The Hadrons and the Leptons. The leptons are fundamental particles, meaning
that they are not made up of quarks. Hadrons are non-fundamental, meaning
they are made up of quarks. Hadrons have 2 sub-groups: the Baryons and the
Mesons. They can both be made of matter and anti-matter. They can also bot be
affected by gravitational interaction and electromagnetic interaction

- Name all the Leptons and
Hadrons.
- Hadrons: Mesons - Kaon and Pion,
Baryons - Proton and Neutron
- Leptons: Electron,
Electron neutrino, Muon,
Muon neutrino, Tau, Tau
Neutrino
- Hadrons: Mesons - Kaon and Pion,
Baryons - Proton and Neutron
- To check the conservation of a
reaction, you can check: Lepton
number, Baryon number,
Charge
- What are the 4
Fundamental forces?
- Gravity, Electromagnetic
Force, Strong Nuclear Force
and Weak Nuclear Force
- What is the Strong Nuclear Force?
- The force that prevents the protons inside the nucleus from
repelling each other and causing the atom to 'fall apart'. it is
between 0.5 and 3 fm. It holds the protons and neuteons
together.

together.
- What is the Weak Nuclear Force?
- This is responsible for Beta- decay. It is
mediated by W and Z bosons shown in
Feynman Diagrams
- This is responsible for Beta- decay. It is
mediated by W and Z bosons shown in

- What is the Strong Nuclear Force?
- Gravity, Electromagnetic
Force, Strong Nuclear Force
and Weak Nuclear Force
- What are the different
flavours of quark?
- Up - Down - Strange -
Charm - Top - Bottom
- Up - Down - Strange -
