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.
