A compound of sulfur with a metal or with another element — sulfur combined with something else, where the sulfur has not been joined to oxygen. The one everybody has met without knowing its name is hydrogen sulfide, the gas that smells of rotten eggs; it is what you smell near hot springs, drains and mudflats, and it is genuinely dangerous in quantity, which is worth remembering because at high concentrations it stops smelling and people think the danger has passed. Others turn up in mining and geology, because many metal ores are sulfides — iron sulfide (fool's gold is one form), lead sulfide, zinc sulfide.

A compound of sulfur with a metal or with another element硫跟金屬或其他元素形成的化合物 sulfur combined with something else也就是硫跟別的東西結合 where the sulfur has not been joined to oxygen但硫沒有跟氧結合 The one everybody has met without knowing its name大家其實都聞過、卻不知道名字的那個 is hydrogen sulfide就是hydrogen sulfide硫化氫 the gas that smells of rotten eggs那種聞起來像臭雞蛋的氣體 it is what you smell就是你在 near hot springs, drains and mudflats溫泉、水溝，還有泥灘附近聞到的味道 and it is genuinely dangerous in quantity而且份量多的時候真的很危險 which is worth remembering這點值得記住 because at high concentrations因為濃度高的時候 it stops smelling它反而聞不到味道了 and people think the danger has passed讓人誤以為危險已經過去 Others turn up in mining and geology其他的硫化物則出現在礦業和地質學裡 because many metal ores are sulfides因為很多金屬礦石都是硫化物 iron sulfide像硫化鐵 (fool's gold is one form黃鐵礦就是其中一種) lead sulfide硫化鉛 zinc sulfide還有硫化鋅

This f spelling is the American one; British writing traditionally uses sulphide. As with sulfate, the international chemistry body settled on the f, so science writing everywhere now uses sulfide.

This f spelling這個用f的拼法 is the American one是美式拼法 British writing traditionally uses sulphide英式寫法傳統上用sulphide As with sulfate就像sulfate一樣 the international chemistry body settled on the f國際化學組織後來定案用f sulfide so science writing everywhere now uses sulfide所以現在全世界的科學寫作都用sulfide這個拼法

Keep the ending straight: -ide means sulfur joined directly to another element, -ate means a salt of sulfuric acid, with oxygen in it. Different endings, different compounds, and the exam will ask.

Keep the ending straight要把字尾分清楚 -ide means sulfur joined directly to another element -ide表示硫直接跟另一個元素結合 -ate means a salt of sulfuric acid而-ate表示硫酸鹽 with oxygen in it裡面含有氧 Different endings, different compounds不同的字尾就是不同的化合物 and the exam will ask考試也會考這個
