锝
1、一种结晶状的放射性金属元素,化学性质与铼、锰类似,首次得到锝元素是用重氢或中子撞击钼,并且也是铀的裂变产物之一 ——元素符号为Tc。
作为Masurium,它是在自然界中发现的第一种只能通过自然裂变产生的元素;作为锝,它是在实验室中发现的第一种元素。
As Masurium, it was the first element discovered that occurs in nature only from spontaneous fission, and as Technetium, it was the first element discovered in a laboratory.
