早在1871年门捷列也夫就予言了原子序数为43的元素的存在,并称它为类锰,同时还确定了该元素在周期表中的位置。为了证实这一元素的存在,许多科学家进行了大量的在矿石中寻找它的工作。但是很长时间并没有发现这个元素。直到1937年意大利物理学家谢格尔(Ssgre)和别瑞耳(Perrier)用氘核撞击钼核的人工方法才得到了43号元素。这是第一个用人工方法获得的元素。将它命名为“锝”(Tc),意思是人工得到的。后来,人们还研究了得到这一元素同位素的许多方法。目前,相当量的锝来自铀核
As early as 1871, Mentelevich gave the existence of an element with an atomic number of 43 and called it manganese-like. He also determined the position of the element in the periodic table. In order to confirm the existence of this element, many scientists conducted a lot of work to find it in ore. However, this element has not been found for a long time. It was not until 1937 that the Italian physicists Ssgre and Perrier got the No. 43 element by the artificial method that the helium nuclear hit the molybdenum core. This is the first element obtained manually. Name it “” (Tc), which means artificially obtained. Later, people also studied many ways to get this elemental isotope. At present, a considerable amount of helium comes from uranium
