•Gold is attractive and used for jewellery
•Steel is an alloy of iron and made sharp for cutting
•Copper is good at conducting heat
•Iron is strong and has high tensile strength
•Tin cans do not corrode
•Aluminium is light and is used in aircraft construction
Physical Property & Link with Structure of Metals
1 malleable (easily bent) and ductile (easily stretched)
Reason: layers of metal atoms can slide over each other easily
2 high density
Reason: close packing of metal atoms
3 good conductors of heat and electricity
Reason: contain electrons which are free to move throughout the metal
4 high melting and boiling points
Reason: a lot of energy is required to weaken and break the strong bonds
