Revision lesson.  Metals found in the ground are normally found as a METAL ORE – combined with other elements in compounds  Metals found on their own.

M. Rahman C1 TOPIC 4 1) Why are gold and platinum found in the ground as uncombined elements? Answers Unreactive-don’t react with oxygen.

Metals can be either ferrous or non-ferrous. Ferrous metals contain iron while non-ferrous metals do not.Metals can be either ferrous or non-ferrous.

Suitability of metals cwk date Task - Find the metals

Task - Match the metal to it’s use Suitability of metals cwk date Task - Match the metal to it’s use Making jewellery. Electrical cables. Compounds of this metal are essential for healthy bones and teeth. Making aeroplanes. Making buildings. This is a liquid metal found in thermometers. Compounds of this metal are used in hospital scans to help show digestive systems clearly on an X-ray. Fishing weights.

Suitability of metals cwk date Alloys

Suitability of metals cwk date Types of Steel

Here are some examples of common alloys: Suitability of metals cwk date Here are some examples of common alloys: Bronze Bronze is an alloy of copper and tin. It's harder than copper and it's good for making medals and statues from. Each side column item (e.g. an image, a tip, a video link) goes in its own sidebox construct Button to be shown when the side column is hidden go outside of the shift div Cupronickel Cupronickel is an alloy of copper and nickel. It's hard and corrosion-resistant. It's used to make “silver” coins. Gold alloys Gold alloys are used to make jewellery as pure gold is too soft. Metals such as zinc, copper, silver, palladium and nickel are used to harden the “gold”. Aluminium alloys Aluminium alloys are used to make aircraft. Aluminium has a low density, but it's alloyed with small amounts of other metals to make it stronger.
