铍元素及其同位素的发现:思想进步与方法发展的结晶

Discovery of Beryllium and Its Isotopes: The Crystallization ofIdeological Progress and Methods Development

1798年,法国化学家沃克兰通过对“绿柱石和祖母绿”分析研究,捕捉到未知元素存在的迹象,提出铍元素假说;19世纪,原子-分子论和元素周期表的建立使铍元素的原子量得以确定,形成“Be”的符号表征,推动了铍元素假说的发展。1898年,法国化学家勒博利用电解法成功制备出铍金属单质,使铍元素假说得到证实。20世纪20年代,铍同位素的发现,使人们对铍元素有了新认识。总之,铍元素及其同位素的发现史,既是铍元素概念形成和发展的历程,也是科学思想进步和科学方法发展的结晶。

In 1798,the French chemist Vauquelin based on the analysis of“beryl and emerald”,caught the signs of the unknown element and put forward the beryllium element hypothesis;In the 19th century,the establishments of the atom-molecular theory and the periodic table of elements determined the atomic weight of beryllium,formed the symbolic representation of“Be”,and promoted the development of the beryllium hypothesis.In 1898,French chemist LeBeau successfully prepared beryllium metal element by electrolysis,which confirmed the beryllium element hypothesis.In the 1920s,the discovery of beryllium isotopes led to a new understanding of beryllium element.In short,the discovery history of beryllium element and its isotopes is not only the process of the formation and development of the concept of beryllium element,but also the crystallization of the progress of scientific thought and scientific methods.
