Matter Lesson 5

OUTCOME

By the end of this lesson you will be able to explain the difference between matter and antimatter. You will be able to explain what cosmic radiation is and recognise the large array of different subatomic particles and be able to identify examples of Hadrons and Leptons.

Reading p. 208 - 212

The standard model describes how all matter is formed out of fundamental particles

Subatomic particles come from two fundamental particles, leptons and quarks. Quarks combine to create hadrons which in turn are grouped as mesons and baryons. protons and neutrons are baryons. Electrons are leptons

1. What are fundamental particles?

2. Write out the taxonomy if the particle zoo into your notes.

3. What type of particles do quarks combine to make?

4. How are these particles related to protons and neutrons?

5. what is an anti-particle?

6. What happens when particles and antiparticles interact?
