The Reactivity Series | 反应性序列

📚 The Reactivity Series | 反应性序列

The reactivity series is a list of metals arranged in order of how vigorously they react with other substances, such as oxygen, water, and acids. It helps chemists predict whether a metal will take part in a reaction, how a metal can be extracted from its ore, and how easily a metal will corrode.

反应性序列是一张按金属与其他物质（如氧气、水和酸）反应的剧烈程度排列的金属顺序表。它帮助化学家预测金属是否会参与反应、金属如何从矿石中提取，以及金属腐蚀的难易程度。

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

The reactivity series is a way of arranging metals in order of their reactivity, from the most reactive to the least reactive. A metal’s reactivity describes how easily it loses electrons and forms positive ions in chemical reactions.

反应性序列是将金属按照活泼性从强到弱排列的一种方式。金属的活泼性描述它在化学反应中失去电子并形成正离子的难易程度。

In KS3 Chemistry, a common order is: potassium, sodium, calcium, magnesium, aluminium, carbon, zinc, iron, lead, hydrogen, copper, silver, gold.

在 KS3 化学中，常见顺序为：钾、钠、钙、镁、铝、碳、锌、铁、铅、氢、铜、银、金。

Carbon and hydrogen are not metals, but they are included as useful reference points. Carbon helps explain which metal oxides can be reduced by heating, and hydrogen helps predict acid reactions.

碳和氢不是金属，但作为有用的参照点被列入序列。碳有助于解释哪些金属氧化物可以通过加热还原，氢则有助于预测金属与酸的反应。
