One way to hold barium: a soft silver-white metal that almost never appears on its own. It is so eager to react that people meet it as a compound instead — a white powder in paint, or a white liquid in a hospital. The name points at the substance; the situation tells you which form of it you are dealing with.
可以想成:barium 是一種很軟的銀白色金屬,但它幾乎不會單獨出現。它太容易起反應了,所以人們實際碰到的,多半是它的化合物——顏料裡的白色粉末,或醫院裡那杯白色的藥水。名字指的是同一種物質,是情境在告訴你,眼前是它的哪一種樣子。
From the word’s history
Coined by the British chemist Humphry Davy in 1808, from baryta (a mineral name) plus the ending -ium, which English uses for metal elements.
這個名字是英國化學家 Humphry Davy 在 1808 年取的,由礦物名 baryta 加上金屬元素常見的字尾 -ium 組成。所以字面上可以想成「從 baryta 裡取出來的那個金屬」,這也解釋了為什麼這個字一開始就是實驗室裡的字。
