Metals in Chemistry for GCSE

Metals are a group of elements that have certain properties in common. They are good conductors of heat and electricity, they are malleable and ductile, and they tend to form positive ions.

Reactivity Series

Metals can be arranged in order of their reactivity, with the most reactive at the top and the least reactive at the bottom. This is known as the reactivity series. The reactivity series is:

1. Potassium

2. Sodium

3. Lithium

4. Calcium

5. Magnesium

6. Aluminium

7. Zinc

8. Iron

9. Tin

10. Lead

11. Hydrogen

12. Copper

13. Silver

14. Gold

Extraction of Metals

Metals can be extracted from their ores using a variety of methods. The method used depends on the reactivity of the metal. For example, metals that are less reactive than carbon can be extracted by heating the ore with carbon. This is known as reduction.

Properties of Metals

Metals have a number of useful properties that make them important in industry. For example, they are good conductors of heat and electricity, which makes them useful in electrical wiring. They are also malleable and ductile, which means they can be easily shaped into different forms.

Uses of Metals

Metals have a wide range of uses in industry and everyday life. For example, iron is used to make steel, which is used in construction and manufacturing. Aluminium is used in packaging, construction, and transportation. Copper is used in electrical wiring and plumbing. Gold and silver are used in jewelry and coins.
