 [Extra information: Metals: Metals are elements that are malleable, ductile, and can conduct electricity. Examples: Sodium, Potassium, Copper, Aluminium, Mercury and sodium are metals. 

Platinum, gold and silver are used to make jewellery because these are malleable and ductile. These are highly resistant to corrosion.

Sodium, potassium and lithium are very reactive and catch fire when exposed to air. This is due to their low ignition temperature and high reactivity. Aluminium forms a non-reactive layer of aluminium oxide on its surface. This layer prevents aluminium to react with other substances. That’s why aluminium is used to make cooking utensils. Sodium is a metal that is so soft that it can be cut with a knife. Silver is the metal that is the best conductor of heat and electricity. ]
