Xenon is one of the chemical elements — a gas with no colour and no smell. There is a tiny amount of it in the air we breathe, so small that you could never notice it. Its symbol is Xe. It belongs to the group chemists call the noble gases, which means it almost never joins with other things; it just stays itself.

Xenonxenon is one of the chemical elements是化學元素之一 — a gas with no colour and no smell是一種無色無味的氣體。There is a tiny amount of it in the air we breathe我們呼吸的空氣裡有極微量的它, so small that you could never notice it少到你根本不可能察覺。Its symbol is Xe它的元素符號是Xe。It belongs to the group chemists call the noble gases它屬於化學家稱為noble gases（惰性氣體）的那一族, which means it almost never joins with other things意思是它幾乎不會跟其他東西產生反應; it just stays itself就是一直保持自己原本的樣子。

Where students actually meet the word is in lights: put xenon in a lamp and send electricity through it, and it gives a very bright white-blue light. Car headlights that look brilliantly white instead of yellow are often called xenon headlights (also called HID lights), and the flash in older cameras and in lighthouses used xenon too. So the word lives in two places — the chemistry textbook, and the shop where people talk about car lamps.

Where students actually meet the word is in lights學生真正會遇到這個字的地方是在燈具上: put xenon in a lamp and send electricity through it把xenon放進燈裡通電, and it gives a very bright white-blue light就會發出非常明亮的白藍色光。Car headlights that look brilliantly white instead of yellow看起來是亮白色而不是黃色的車頭燈 are often called xenon headlights (also called HID lights)常被稱為xenon headlights（也叫HID燈）, and the flash in older cameras and in lighthouses used xenon too舊式相機的閃光燈和燈塔的燈光，也用過xenon。So the word lives in two places所以這個字活在兩個地方 — the chemistry textbook, and the shop where people talk about car lamps一個是化學課本，一個是討論車燈的店家。

It is a noun and you do not put "a" in front of it: say "xenon" or "xenon gas", not "a xenon". The first sound is /z/, not /ks/ — "ZEE-non".

It is a noun and you do not put 'a' in front of it它是名詞，前面不加「a」: say 'xenon' or 'xenon gas', not 'a xenon'要說「xenon」或「xenon gas」，不要說「a xenon」。The first sound is /z/, not /ks/開頭的音是/z/，不是/ks/ — 'ZEE-non'唸作「ZEE-non」。
