摘要:

镧系元素是第57号元素镧到71号元素镥15种元素的统称。它们的化学性质相似,在生产、生活中起着重要的作用。本文假想镧系元素失踪后地球发生的一系列变故,借此体现它们在人类生活中的重要性。

关键词: 镧系元素, 发现, 性质, 应用

Abstract:

The lanthanides include elements having atomic numbers 57 (lanthanum) through 71 (lutetium). They all behave in a similar way in chemical reactions and play an increasingly important role in production and life. This article imagines a series of changes that have taken place on the earth since the disappearance of lanthanides, which shows their importance in human life.

Key words: Lanthanide, Discovery, Property, Application
