Name 7 Metals that you know ....
Gold, Copper, Silver, Zinc, Aluminium, Steel, Brass, Tin, Nickle, Iron, Cobalt, Chromium, Bronze, Platinum, Lead,
now check the periodic table and
Write a 'e' beside any of these metals that are elements.
Name any property that you think different metals share?
- Hard / strong
- Bendable (but often stiff)
- Meltable (do not burn)
- Ring when struck (sonorous)
- Metals react with Oxygen
- Conduct Heat
- Conduct electricity
- Most are Solids
- Can Be Magnetic
A metal is a substance that generally allows its outer electrons to flow so ..... metals conduct heat and electricity. Metals also like to react with non metallic elements like oxygen.
Follow this link to find out more about metals and the way they remain as solids.

OC48 describe the general properties of the alkali metals and understand that alkali metals are in Group I of the Periodic Table and have similar properties
OC50 understand that Group II elements are the alkaline earth metals
OC51 investigate the reaction between zinc and HCl, and test for hydrogen (word equation and chemical equation)
An aluminium cable is half the weight of a copper one with the same rating, so aluminium cables (reinforced with steel) are often preferred for hanging between overhead pylons.

Table showing relative metal costs
The table below can only really be used to give broad relative initial material costs. The figures are based on a
