This topic is about learning what is inside a nucleus and essentially how does that make an atom behave. You really need to learn a lot of basic facts. You can also find loads of youtube movies, just search for the key terms and you will learn lots of things.
This is a test designed to check if you understand Chapter 2 of the work you have completed. Only attempt this quiz when you have revised or you will not get a top score.
When you get a score you are happy with let you teacher know so they can put it in their markbook.
Congratulations - you have completed AS Chapter 2 Quarks and Leptons.
You scored %%SCORE%% out of %%TOTAL%%.
Your performance has been rated as %%RATING%%

Which choice best describes a muon....
The muon is unstable with a long mean lifetime of 2.2 µs, it is a lepton and has a charge of -1.6 x 10^(-19)C. It always decays into two particles.
The muon is unstable with a long mean lifetime of 2.2 µs, it is a lepton and has a charge of -1.6 x 10^(-19)C. It always decays into three particles.
The muon is stable and has a charge of -1.6 x 10^(-19)C
The muon is unstable with a long mean lifetime of 22 µs, it is a lepton and has a charge of +1.6 x 10^(-19)C. It always decays into three particles.

Which statement about a kaon is all true....
They contain a double strange or anti-strange quark.
Kaons decay “strangely” or last a shorter time than they should for their mass.
