Izzy Ps Party Flashcards
what does A represent when discussing an atom
The nucleon number (the number of protons + neutrons)
What does a represent when discussing an atom
The proton number
What is the charge of proton
1.6 x 10^-19
What is the charge of an electron
-1.6x10^-19
What is the charge of a neutron
0
What is the mass of an electron
9.11 x 10^-31
What is the mass of a proton
1.673 x 10^27
What is the mass of a neutron
1.675 x 10^-27
Define isotope
An element with the same number of protons and electrons but a different number of neutrons
Define specific charge
It is the ratio of charge to mass
What is the equation for specific charge
Specific charge = charge (C) / mass (Kg)
What is the unit for specific charge
CKg^-1
What are antiparticles
They are the opposite of a particle with the same mass with opposite charge
What is the antiparticle of an electron
Positron
What is annihilation
When a particle and antiparticle collide they produce TWO photons of energy
What is a photon
A packet of energy
What is pair production
A SINGLE photon of energy with a minimum rest energy produces a particle antiparticle pair
Where does pair production occur
Near a nucleus
What is the equation for creation and annihilation
E(rest) = m x c^2
What is a quark
Fundamental particles
What are the 3 types of quarks you need to know
Up down and strange
What is the charge, baryon number and strangeness of a up quark
C = 2/3 B = 1/3 S = 0
What is the charge, baryon number and strangeness of a Down quark
C=-1/3 B=1/3 S=0
What is the charge, baryon number and strangeness of a strange quark
C=-1/3 B=1/3 S=-1
What is the strangeness of a S antiparticle
1
What are baryons
Particles made by 3 quarks
What are mesons
Particles made by a quark antiquark duo
Name the two types of baryons
Protons and neutrons
Name two types of mesons
Kaon and pion
Composition of a kaon plus
Up anti strange
Composition of kaon minus
Anti up strange
Composition of pion plus
Up anti down
What is the rest energy of an electron
0.51MeV
What are leptons
Another type of fundamental particle
What are the 6 leptons
Electron
Electron neutrino
Muon
Muon neutrino
Tauon
Tauon neutrino
What 3 things must be conserved
Charge
Baryon number
Lepton number
When is strangeness conserved
Everywhere except in weak interaction (decays)
When is they strong force repulsive for neutron neutron or proton neutron
0-0.7Fm
When is the strong force strongly attractive for neutron neutron and neutron proton?
0.7-3Fm
When is the strong force neutral for proton neutron or neutron neutron
5fm
When is the electromagnetic force and strong force repulsive for proton proton
0-0.7fm and 2+(weak)
When is the strong force and electromagnetic force attractive
0.7-2
What do you say when entering the function
Hello huzz
What to do if a huzz wants to dance
Flowberry jizz everywhere
What should you say if you would like a hug from a lovely lady
Where my hug at? 🥹
