1State the reactivity series
Potassium,Sodium,Lithium,Calcium,Magnesium,Carbon, Zinc,Iron,Hydrogen,Copper
2What happens the more reactive the metal?
It loses electrons easier and becomes cations and has stronger reactions.
3How do metals react with water?
Potassium and Sodium- violently
Calcium, Magnesium- Slow with cold water, rapid with steam
Iron- rusts slowly
4How do metals react with acids?
Potassium and sodium- violently
Aluminium, Magnesium,Calcium- rapid
Zinc, Iron- slowly
5What are redox reactions?
chemical reactions that transfer electrons between reactants. Oxidation and reduction. Also known as displacement reactions
6What does OIL RIG stand for?
oxidation is loss, reduction is gain (of electrons)
7Where are most metals found?
In the Earth's crust and are extracted from ores
8Where are unreactive metals found?
Unreactive metals such as gold are found in the Earth's crust as uncombined elements
9What is oxidation?
Loss of electrons, gain of oxygen
10What is reduction?
gain of electrons, loss of oxygen
11How are metals extracted?
By reducing their ores
12How are metals extracted by reacting with carbon?
Any metal less reactive than carbon can be displaced with it. Displacement isn't used for more reactive metals as it would be too expensive
