摘要
18世纪末,伴随着分析化学的发展,科学家先后对新发现的矿物“叶长石”展开研究。19世纪初,瑞典化学家阿尔费德森发现该矿物中含有一种性质未知的固定组分,意识到一种新元素的存在并提出有关锂元素的猜想。1818年,英国化学家戴维通过电解法首次制得金属锂单质,锂元素的猜想得以证实。20世纪初,锂元素同位素的发现,使人们对于锂元素的内涵有了新的认识。总之,随着科学思想和科学方法的不断发展,锂元素概念的内涵也在不断发展变化。
At the end of the 18th century,with the development of analytical chemistry,scientists successively studied the newly discovered mineral“petalite”.In the early of the 19th century,Swedish chemist Arfwedson found that the mineral contained a fixed component with unknown properties.He was aware of the existence of a new element and put forward a hypothesis about lithium.In 1818,British chemist David prepared metal lithium by electrolysis for the first time,and the lithium hypothesis was confirmed.In the early of 20th century,the discovery of lithium isotopes made people have a new understanding of the concept of lithium.In short,with the continuous development of scientific thoughts and methods,the connotation of the concept of lithium is also developing and changing.
