钾元素概念的发展史及其意义

The Development History of the Concept of Potassium and It’s Significance

通过对钾元素概念的发展史考证分析可知,钾是电化学兴起后最先发现的活泼金属。19世纪初,随着科学思想和实验条件的发展,通过电解法首次制取到钾的单质,但并未确定为元素。19世纪中期,对钾元素性质的实验验证和原子论的发展,使得钾元素的概念被确认。20世纪20年代,钾元素同位素的发现,形成了现代的钾元素概念。钾元素概念的发展史不仅是元素概念的发展史,也是科学方法的发展史与科学思想的演变史。

Through the research and analysis of the development history of the concept of potassium, it can be recognized that potassium is the first active metal found after the rise of electrochemistry. In the early 19 th century, with the progress of scientific ideas and experimental conditions, potassium was the first prepared by electrolysis, but it was not identified as an element. In the middle 19 th century, experimental verification of the potassium properties and the development of atomism led to the potassium concept was confirmation. The discovery of potassium isotopes in the 1920 s formed the modern concept of potassium. Development history of potassium concept is not only the elements concept progressive process, but also the evolution history of the scientific methods and scientific ideas.
