Properties Of Metals
Metals are all basically the same with only thew differences. They have the same basic properties, but each when combined with other metal elements have a special combination which makes it considerably stronger.
METALS ARE STRONG AND BENDY AND THEY'RE GREAT CONDUCTORS!
One thing that's important to realise, the periodic table is compiled of mostly metals (the far right are the only non metals).
What you must realise, is that all metals have fairly similar properties.
1) Metals are strong (hard to break), but they can be bent or hammered into different shapes (depending what they're being used for).
2) They are great conductors of heat (because of free electrons - Physics P1)
3) and they also conduct electricity well.
Metals (epically metals which are referred to as 'transition metals' which can be found in the central block of the periodic table) have loads of everyday uses because of their properties such as:
1) Their strength and 'bendability' makes them handy for making into bridges and car bodies.
2) Metals are extremely useful if you want them to conduct heat (get hotter) which is useful for equipment like saucepans and frying pans. (Of course how much heat a metal does conduct depends on its main element and it's colour - Physics Topic P1).
3) And their conductivity make them extremely useful where electricity is concerned i.e. making electrical wires (copper is perfect for this)
Metal's Exact Properties
The properties listed on previous cards are a metals typical properties. Unfortunately, for you, you have to learn the properties of three very important metals which are:
Copper :- Copper as I have mentioned before is a good conductor of electricity. This means it can be used for electrical wiring. Another reason it's used for electrical wiring is because it's hard and strong but easily bent. And it doesn't react with water!
Aluminium :- Aluminium is low-density and corrosive resistant. Unfortunately, aluminium isn't a strong metal in its pure form but can be used to create strong alloys (which eventually can be used for planes).
Titanium :- Titanium, like aluminium is a low-density and corrosive resistant metal. But un-like aluminium, it's incredibly strong (this is used on more modern and faster planes due to its strength). Unfortunately, it has a weakness, due to it having a higher atomic mass that aluminium, it weighs more, which means a plane has to have bigger stronger engines to carry a titanium plane!
