lanthanum

英 ['l?nθ?n?m] 美['l?nθ?n?m]
  • n. [化學(xué)] 鑭

中文詞源


lanthanum 鑭

來自PIE*ladh,隱藏,詞源同latent.因該元素發(fā)現(xiàn)之艱難而得名。比較dysprosium.

英文詞源


lanthanum (n.)
metallic rare earth element, 1841, coined in Modern Latin by Swedish chemist and mineralogist Carl Gustav Mosander (1797-1858), who discovered it in 1839, from Greek lanthanein "to lie hidden, escape notice," from PIE root *ladh- "to be hidden" (see latent). So called because the element was "concealed" in rare minerals.
