Question 5

What are all the different types of particles?

Answer 5

HADRONS, baryons, mesons, LEPTONS

Question 6

What is the difference between Hadrons and Leptons?

Answer 6

Hadrons are made up of quarks, leptons are not as they are fundamental particles

Question 7

Give 2 examples of baryons?

Answer 7

Protons and neutrons

Question 8

Give 2 examples of mesons?

Answer 8

Pions and Kaons

Question 9

How are particles classified as baryons or mesons?

Answer 9

Baryons are made up from 3 quarks whereas Mesons are made up from a quark anti-quark pair which makes them less stable and allows them to decay into fundamental particles

Give 2 examples of leptons?

Answer 10

Electrons, positrons, muons, neutrinos and anti-neutrinos
