• n. [化學(xué)] 鉭（符號(hào)Ta，原子序73）

金屬元素，命名來(lái)自拉丁語(yǔ) Tantalus,因這種金屬元素不溶入酸，如果 Tantalus 一樣干著急。

tantalum (n.)

metallic element, 1809, Modern Latin, named 1802 by its discoverer, Swedish chemist Anders Ekberg (1767-1813), for Tantalus, according to Ekberg partly because of its inability to absorb acid recalled Tantalus' punishment in the afterlife (see tantalize). Sometimes it is said to be so called from the difficulty scientists faced in obtaining a pure specimen.
