The Reactivity Series Flashcards
What are ores
Rocks that contain metals and metal compounds - they are usually metal oxides
What is very reactive elements
Potassium
Sodium
Calcium
What are the fairly reactive elements
Magnesium
Alluminium
Carbon
Zinc
What are the not very reactive elements on the reactivity series
Iron
Lead
Hydrogen
Copper
Whjat are not at all reactive elements on the reavctivity series
Silver and gold
What happens as you go up the reactivity series
Reactivity increases
How are the top 5 elements extracted
By electrolosis
What is electrolosis
It is when electricity splits up the ore into its elements
Howare zinc iron and copper extracted
Thye are extracted from their ores by reduction using carbon
Where are silver and gold extracted from
They are found in the earth in there pure form
What is reduction using carbon
It is when an ore is reduced, oxygen is removed from it
