rusting1.gif1. Many metals are affected by the in air and in contact with , which both cause them to '' like iron.

2. The 'light' metal is useful for many structural uses because it doesn't easily.

gold1.gif3a. However, there is quite a range in reactivity and so metals like do not 'rust' but (or steel) readily does.
3b. This corrosion in iron is due to the formation of an orange or iron .

4a. The potassium, and lithium are unusually and easily cut into lumps.
4b. When freshly cut the surface is typical of metals eg , but rapidly becomes as they corrode in air.

copper3.gif5. The metal is used for roofing and tarnishes to form a dull looking compound.

6. Generally speaking the more a metal, the more it corrodes.
