molybdenum (n.)youdaoicibaDictYouDict[molybdenum 词源字典]
metallic element, 1816, from molybdena, used generally for lead-like minerals, from Greek molybdos "lead," also "black graphite," related to Latin plumbum "lead" (see plumb (n.)), and like it probably borrowed from a lost Mediterranean language, perhaps Iberian. The element so called because of its resemblance to lead ore.[molybdenum etymology, molybdenum origin, 英语词源]
