Subatomic Particles
The charge of a neutron?
ZERO - NEUTRAL - NO CHARGE
What does a particle accelerator do?
moves particles around a circular track at speeds close to the speed of light, until particles collide. Then they will study the debris from the explosion!
The proton and neutron are made up of Up quarks and ______________________.
Down Quarks
Charm is one of the flavours of __________.
QUARKS
Name the 2nd generation leptons
Muon, muon neutrino
Negative charge, located in an atomic orbital around the nucleus
THE ELECTRON
* bonus 100 pts - draw a picture to represent the atomic orbital/probability cloud*
What is the most famous particle that the Large Hadron Collider discovered called?
The Higgs Boson Particle
Draw the quarks in a Proton
(2 up quarks and 1 down quark + gluon holding them together)
What is the nucleus?
The center of the atom - where the protons and neutrons are found
What is the charge of a tau neutrino?
0
IN THE NUCLEUS, A CHARGE OF +1
How does the particle accelerator cause the particles to move around the 'race track'?
MAGNETS!
Name 4 of the 6 flavours of Quarks?
UP
DOWN
STRANGE
CHARM
TOP
BOTTOM
what is gluon?
the 'glue' that holds quarks together
Which is heavier: an electron or electron neutrino?
Electron
Where are protons and neutrons found?
The Nucleus
What is the Higgs Boson Particle?
The particle that gives EVERYTHING its mass
Draw the Quarks that make up the neutron:
(2 down quarks + 1 up quark + gluon)
What kind of particle is an electron?
an electron is a type of lepton, which is an elementary particle.
Formula for lepton number
L=no leptons - no. antileptons
what is a composite particle vs. an elementary particle?
COMPOSITE: made up of still smaller parts (neutron made up of quarks)
ELEMENTARY: can not be broken down into smaller parts (electrons)
What do some people fear the particle collider will accidentally create?
A black hole
Do electrons contain quarks? Why/why not?
NO! They are elementary particles meaning they cannot be broken down into smaller parts.
How fast do particles move around the track of the Large Hadron Collider (approximately)
99.999% the speed of light!
What are leptons made of?
Themselves, they are a fundamental particle
