There are 2 main methods for extracting metals from their ores - reduction with carbon and the electrolysis.
Explain, with suitable examples, how the extraction method relates to the position of the metal in the reactivity series.

✔ 最佳答案
Hints:Reactivity series actually means the reactivity of different common metals in sequence
.
Reactivity series is as follows:
K > Na > Ca > Mg > Al > Zn > Fe > Pb > Cu > Ag > Pt > Au
For higher reactive metals, the more difficult to be extracted.
And now you should know how to write your essay.
參考: Knowledge is power.

SORRY呀~原來本書真係有講到~但係我都有d野唔明呀~其實係唔係果樣element個reactivity愈高,個electronic arrangement就愈唔stable呢? 錦係唔係因為果樣element既electronic arrangement唔stable,所以就難d extract呢?錦gold同silver既electronic arrangement係唔係好stable嫁?但係gold同silver都唔係group 0...

obviously, this is YOUR homework.
no one should give you answers; not even hints, as this can be READILY found in textbooks.
let us know WHAT / Which parts do you NOT understand.
