摘    要:1871年,门捷列夫依据元素周期律和元素周期表预见了“类锰”(即锝元素)的存在;至20世纪,随着科学家对原子核变化的研究进展、回旋加速器的发明以及人工放射性元素的发现,化学家和物理学家一起用回旋加速器加速的氚核轰击钼靶得到了锝元素。锝成为了第一个人工合成的元素,是化学家与物理学家合作的结晶。它的发现不仅显示了先进的科学方法和科学仪器的重要作用,也证明了学科间合作的重要性。

关 键 词:锝元素  化学模型  人工合成元素

Abstract:In 1871, Mendeleev predicted the existence of "eka-manganese" (technetium element) based on periodic law of elements and Periodic table of elements; to the 20th century, with the progress of the research on nuclear changes, the invention of cyclotrons and the discovery of artificial radioactive elements, chemists and physicists bombarded molybdenum targets with tritium nuclei accelerated by cyclotron to obtain technetium. Technetium became the first synthetic element, which was the crystallization of cooperation between chemists and physicists. Its discovery not only shows the important role of advanced scientific methods and scientific instruments, but also proves the importance of interdisciplinary cooperation.
Keywords:technetium element  chemical model  synthetic element
