All elements have certain characteristics such as how they react with other substances or their melting transfer, hardness and so on These characteristics are known as their properties. Most metals have the pursuit properties in reciprocal:
* Solids at room temperature (melting and boiling point usually ranging between 1200°C and 2000°C).
* Good film directors of heat and electrical energy (this is beca role delocalized electrons throw the current/heat energy around the metal).
* bendable (can be bent or hammered into shapes without breaking)
* Ductile (can be stretched into wires)
* Hard & Strong (giant lattice structures)

Iron is the cheapest and most widely used metals but pure press is not suitable for most uses. Iron is usually combine with other elements, e.g. carbon, vanadium, manganese and chromium, to make materials called alloys. Steel is a common alloy of carbon iron with less than 2% carbon. unalike pure iron, stigma is hard and strong so is profitable for making girders for construction purposes (buildings and bridges). It is also bendable and thin steel sheet can be pressed into shapes, e.g. car proboscis panels. Iron and steels will react with moist air to mark rusty which weakens the metal.
Steel that is alloyed with chromium does not rust it is called stainless steel and is used in the manufacture of sinks and cutlery.

Copper is malleable, ductile and a in truth good conductor of electricity. These properties make it suitable for use as electrical wiring. Since papal bull is an unreactive metal it is useful for making piping to carry hot water and tanks to store it.
Silver
Silver is a much(prenominal) better conductor of electricity than copper but its use in wiring and circuitry is limited because it is about 250x more pricey than copper (and about 1000x more than iron). Silver is a very unreactive metal and does not tarnish (lose its shiny appearance) easily. It is malleable and ductile and...If you want to get a full essay, effect it on our website: Orderessay
