3. 三種相鄰的放射性元素(92-94號元素),鈾、镎、钚:Uranium, Neptunium, plutonium.
4. 很顯然,這三顆相鄰的行星、這三種相鄰的放射性元素,按照類比的規則有規律地使用了三個神仙的名字來命名。
5. 因為海王星、冥王星在天王星之后緊鄰天王星,同樣地,镎、钚在鈾之后緊鄰鈾元素,所以就是采用這種對應關系來命名了,非常具有統一性和一致性。

中文詞源

英文詞源
- plutonium (n.)
- transuranic element, 1942, from Pluto, the planet, + element ending -ium. Discovered at University of California, Berkeley, in 1941, the element named on suggestion of Seaborg and Wahl because it follows neptunium in the periodic table as Pluto follows Neptune in the Solar System. The name plutonium earlier had been proposed for barium and was sometimes used in this sense early 19c.
