- 1氦、氦氣（派對氣球用的那種；和會燃的氫氣不是同一種）
Helium is a gas, lighter than air, so a balloon filled with it rises. Scientists write it He. It does not burn, which is why party balloons use it; another light gas, hydrogen, can catch fire. A little helium in your mouth makes your voice go thin and high for a few seconds — though actually that is not safe to keep doing, and a teacher will tell you to stop. In science work, very cold liquid helium is used to make big machines extra cold. People first thought this gas was in the sun, so the name was built from the old Greek word for the sun. They added -ium on the end. Though actually, chemists usually keep -ium for metals, and helium is not a metal. The man who probably named it, Norman Lockyer, was looking at the sun, and he did not follow the chemists’ usual rule.
From the word’s history
From New Latin helium, from Ancient Greek hḗlios 'sun' + -ium, as it was first theorised in the Sun's atmosphere.
取自希臘文 hḗlios「太陽」加 -ium，因為最早在太陽上推測到它。
組成From New Latin helium, from Ancient Greek ἥλιος (hḗlios, “sun”), because people first thought it was in the sun’s atmosphere, plus the ending -ium. Probably coined by Norman Lockyer. The -ium ending is unusual here, because it is usually used only for metallic elements; Lockyer was an astronomer and likely did not follow the chemists’ usual rule.
