The Reactivity series Flashcards
Which two “non metals” are useful in the reactivity series and why?
Carbon & Hydrogen because they can also be used to extract metals
Least reactive metals
Cu
Ag
Au
How do you extract the “most” reactive metals
By electrolysis of molten
What is the reactivity series
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom.
Which is more reactive iron or copper?
Iron is more reactive than copper as copper has less outer shells than iron, so copper is less likely to react with another element as it has a stronger hold over the electrons.
Why are metals more reactive?
Metal ions are positively charged as they lose negative electrons. Some metals give up their electrons more readily than others and are, therefore, more reactive.
Is Gold reactive?
least chemically reactive
What is the first in the reactivity series?
Potassium
How do you extract zinc, iron, tin and lead?
Reduction by carbon or carbon monoxide
What is extracting metals low in the activity series?
Metals that are low in the activity series are very un-reactive. The oxides of these metals can be reduced to metals by heating alone.
