Transition Metals: An Overview

The transition metals are placed in the centre of the periodic table, between groups 2 and 3. They are generally hard and dense, and less reactive than the alkali metals. Iron, copper, silver and gold are important transition metals.
The transition metals: overview
The elements in the centre of the periodic table, between groups 2 and 3, are called the transition metals. Most of the commonly used metals are there, including iron, copper, silver and gold
The transition metals
Common properties
The transition metals have the following properties in common: they form coloured compounds they are good conductors of heat and electricity they can be hammered or bent into shape easily they are less reactive than alkali metals such as sodium they have high melting points - but mercury is a liquid at room temperature they are usually hard and tough they have high densities
Iron
Iron is usually made into steel, which is stronger and more easily shaped than iron. Steel is widely used as a structural material, for example to make bridges, buildings, ships and cars.
Copper
Copper is a very good conductor of electricity, so it is used for electricity cables. It is easily bent into shape and it does not react with water, so it is used for water pipes.
Silver
Silver does not corrode in air or water, and it is a very good conductor of electricity. It is used for jewellery, printed circuit boards and electrical contacts.
Gold
Gold does not corrode in air or water, and it is a good conductor of electricity. It is used for jewellery, connecting wires for computer chips and electrical contacts.
