A copper wire, an iron nail, a gold ring and a lump of coal are all made of elements, and they are very different. In this chapter we sort the elements into metals and non-metals, and we see how their properties differ and where the exceptions are. We learn how metals react with oxygen, water and acids, and how the reactivity series puts them in order. Then we find out how a metal and a non-metal join to make an ionic compound, and how metals are got from their ores. Python helps us with the numbers.

Properties of Metals and Non-metals
Why are wires made of copper, and not of sulphur? Why does a bell ring? In this course we compare the physical properties of metals and non-metals, we meet the exceptions, and we learn why metals are mixed to make alloys.
Reactions of Metals and Non-metals
Sodium is kept under oil, and gold never tarnishes. The difference is in how the metals react. In this course we see what metals do with oxygen, water, acids and salt solutions, we arrange them in the reactivity series, and we look at the reactions of non-metals.
