cadmium词源

cadmium (n.)

bluish-white metal, 1822, discovered 1817 by German scientist Friedrich Strohmeyer, coined in Modern Latin from cadmia, a word used by ancient naturalists for various earths and oxides (especially zinc carbonate), from Greek kadmeia (ge) \"Cadmean (earth),\" from Kadmos \"Cadmus,\" legendary founder of Boeotian Thebes. So called because the earth was first found in the vicinity of Thebes (Kadmeioi was an alternative name for \"Thebans\" since the time of Homer).
