「鋁的蘊藏量比金的大很多，為什麼人類早在遠古時期便發現金，但要到較後莆(19世紀)才發現鋁？」
※根據以上句子，才再回答我的發問。※
以上句子的原因除了是鋁比金較難提取外，還有沒有其他原因？
化學小問題！

✔ 最佳答案
因為鋁需要電解先可以獲得`而金掘出黎比水沖下就得到`愈遲發現既金屬大多用電解黎獲得!

Because Al is more reactive than Au.
In nature, we cannot find pure Al, usually is Al compounds. eg. Pure Al foil exposure to air, a thin layer of Al2O3 will form on the surface of the Al foil, but Al2O3 is a good material to prevent the Al foil continue to be oxidized.
Au is least reactive, so mainly be found as pure element state.
