The Reactivity Series | 反应性序列

📚 The Reactivity Series | 反应性序列

The reactivity series is a core idea in chemistry. It places metals in order of how strongly they take part in chemical reactions. By learning this order, you can explain why some metals corrode quickly, why acids bubble with some metals but not others, and how metals are extracted from their ores.

反应性序列是化学中的一个核心概念。它按金属参与化学反应的剧烈程度将金属排序。通过学习这个顺序，你可以解释为什么有些金属腐蚀很快、为什么酸与某些金属反应会冒泡而与其他金属不会，以及金属如何从矿石中提取出来。

In KS3 chemistry, the reactivity series is linked to four key types of reaction: reaction with oxygen, reaction with water, reaction with dilute acids, and displacement reactions. It also helps you understand the extraction of metals using carbon or electricity.

在 KS3 化学中，反应性序列与四类关键反应有关：与氧气反应、与水反应、与稀酸反应以及置换反应。它还能帮助你理解用碳或电提取金属的原理。

1. What Is the Reactivity Series? | 什么是反应性序列？

The reactivity series is a list of metals arranged in order of how readily they react with other substances such as oxygen, water, and dilute acids. The most reactive metals are placed at the top, and the least reactive metals are placed at the bottom.

反应性序列是将金属按照它们与氧气、水和稀酸等其他物质反应的容易程度排列的顺序表。最活泼的金属排在最上面，最不活泼的金属排在最下面。

A metal’s position in the series is linked to how easily it loses electrons to form positive ions. At KS3 level, you can
