2 化合物的命名
化合物的命名顺序都是根据化学式从左往右读， 这与中文读法顺序是相反的。表示原子个数时使用 前缀 (1)mono-,(2)di -,(3)tri- ,(4)tetra – ,(5)penta(6)hexa-,(7)hepta-, (8)octa-,(9)nona-,(10)deca-,但 是在不会引起歧义时，这些前缀都尽可能被省去。

一 无机物的命名 (Inorganic compounds)
1 元素与单质的命名
“元素”和“单质”的英文意思都是“element”，有 时 为 了 区 别 ， 在 强 调 “ 单 质 ” 时 可 用 “ free element”。因此，单质的英文名称与元素的英文名 称是一样的。下面给出的既是元素的名称，同时又 是单质的名称。
or Ferrous
Fe3+ Iron(III)
or Ferric
Cr2+ Chromium(II)
Cr3+ Chromium(III)
Mn4+ Manganese(IV)
Mn2+ Manganese(II)

对于有变价的金属元素，除了可用前缀来表示以外，更 多采用 罗马数字来表示金属的氧化态，或用后缀-ous表示低价，-ic表 示高价。
