在1959年第10期化学通报赠送的门捷列夫元素周期表上,最后的一个元素是第102号元素。102号元素原子量是254,电子结构为5f~(14)7s~2具有α—放射性。它的名称为锘(Nobelium,No)。对于102号元素的发现和存在,目前已经有很多实验证实,这是毫无异议的。但是对于102号元素的名称问题现尚在争论。不过有些周期表都以 No 这个名称填在周期表上,但也有一些最近出版的周期表还 The last element on the Mendeleev’s periodic table presented in the Chemistry Bulletin No. 10 of 1959 is the No. 102 element. The atomic number of element 102 is 254, and the electronic structure is 5f ~ (14) 7s ~ 2 with α-radioactivity. Its name is obel (Nobelium, No). For the discovery and existence of the 102 element, there have been many experiments to confirm that there is no objection. But the name of the 102 element is still debating. However, some periodic tables fill the periodic table with the name No, but there are also some recently published periodic table
