Chosen methodReduction with carbon

Correct?Yes

WhyReactive enough to form a stable ore, but carbon is more reactive than this metal, so carbon displaces it on heating.

Select Potassium (the most reactive metal) and choose Electrolysis — confirm it is correct
Select Iron and choose Reduction with carbon — confirm it is correct
Select Gold (the least reactive metal) and choose Found native — confirm it is correct
Select Aluminium and choose Electrolysis — confirm it is correct, even though Aluminium is not the most reactive on the list
Select Potassium and choose Found native — see why this is WRONG (Potassium is far too reactive)
