英文词源
- 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.
中文解释
1. 天王、海王、冥王:Uranus (希腊神话中的天神乌拉诺斯), Neptune (尼普顿, 相当于希腊神话中的波塞冬:Poseidon), Pluto (普路托, 相当于希腊神话中的哈得斯:Hades).2. 天王星、海王星、冥王星:Uranus, Neptune, Pluto (距离太阳最远的三颗行星,由近及远依次为:天、海、冥).3. 三种相邻的放射性元素(92-94号元素),铀、镎、钚:Uranium, Neptunium, plutonium.4. 很显然,这三颗相邻的行星、这三种相邻的放射性元素,按照类比的规则有规律地使用了三个神仙的名字来命名。5. 因为海王星、冥王星在天王星之后紧邻天王星,同样地,镎、钚在铀之后紧邻铀元素,所以就是采用这种对应关系来命名了,非常具有统一性和一致性。6. 铀、镎、钚:谐音“又拿布”----又把布拿来。
