中英词源

plutonium 钚

来自Pluto,冥王，冥王星，-ium,金属元素。因该金属元素元素周期位于neptunium（Neptune,海王星）之后而命名。

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.
