Ranking the metals
- Some metals react violently; others barely react at all.
- The reactivity series 金属活动性顺序 ranks metals from most to least reactive.
给金属排名
- 一些金属剧烈反应;其他的几乎根本不反应。
- 活泼性顺序(reactivity series)把金属从最活泼到最不活泼排名。
Which of these metals is the most reactive? · 这些金属中哪个最活泼?
Potassium is near the top of the reactivity series. · 钾接近活泼性顺序的顶部。
Put these metals in order from most reactive to least reactive. · 把这些金属从最活泼到最不活泼按顺序排列。
Potassium > magnesium > iron > gold. · 钾 > 镁 > 铁 > 金。
Being very unreactive, ______ is found near the bottom of the reactivity series. · 由于非常不活泼,______在活泼性顺序的底部附近被发现。
Gold is one of the least reactive metals. · 金是最不活泼的金属之一。
The reactivity series
- Metals are listed from most reactive (potassium) to least reactive (gold).
- The order: potassium, sodium, calcium, magnesium, zinc, iron, copper, gold (and more).
The reactivity series ranks metals from most reactive at the top to least reactive at the bottom.
活泼性顺序
- 金属从最活泼(钾)到最不活泼(金)列出。
- 顺序:钾、钠、钙、镁、锌、铁、铜、金(以及更多)。

活泼性顺序把金属从顶部最活泼到底部最不活泼排名。
Displacement and the reactivity series · 置换与活泼性顺序
Step through a displacement. A more reactive metal pushes a less reactive one out of its compound — which is exactly what the reactivity series predicts. · 逐步看一个置换。一种更活泼的金属把一种不那么活泼的从它的化合物中推出——这正是活泼性顺序预测的。
A more reactive metal can: · 一种更活泼的金属能:
More reactive metals displace less reactive ones. · 更活泼的金属置换不那么活泼的。
Displacement reactions
- A more reactive metal will displace 置换 a less reactive one from its compound.
- For example, iron displaces copper from copper sulfate solution.
置换反应
- 一种更活泼的金属会从它的化合物中置换(displace)一种不那么活泼的。
- 例如,铁从硫酸铜溶液中置换铜。
An iron nail placed in copper sulfate solution will: · 一个放进硫酸铜溶液中的铁钉会:
Iron is more reactive than copper, so it displaces it. · 铁比铜更活泼,所以它置换它。
Reactions with water and acid
- The most reactive metals react with cold water; less reactive ones only with acid; the least don't react.
- The series predicts how vigorously a metal will react.
Worked example. Put an iron nail in copper sulfate solution. Iron is more reactive than copper, so it displaces it: the nail gets a copper coating and the blue solution fades. The series predicts the result.
与水和酸的反应
- 最活泼的金属与冷水反应;不那么活泼的只与酸;最不活泼的不反应。
- 这个顺序预测一种金属会反应得多剧烈。
例题。 把一个铁钉放进硫酸铜溶液中。铁比铜更活泼,所以它置换它:钉子得到一个铜涂层而蓝色溶液褪色。顺序预测结果。
You've got it
- the reactivity series ranks metals from most (potassium) to least (gold) reactive
- a more reactive metal displaces a less reactive one from its compound
- the series predicts reactions with water and acid
