Some Common Negative Ions
Negative ions, anions, may be monatomic or polyatomic. All monatomic anions have names ending with -ide. Two polyatomic anions which also have names ending with -ide are the hydroxide, OH-, and the cyanide, CN-.

15
Some Common Negative Ions --- Polyatomic Negative Ions(多原子阴离子)
Many polyatomic anions contain oxygen in addition to another element. The number of oxygen atoms in such oxyanions is denoted by the use of the suffixes -ite and -ate, meaning fewer and more oxygen atoms, respectively. 许多多原子阴离子含有氧和另一种元素。在这些含氧阴离子中,氧原子的数目用后缀 -ate 和 –ite 来表示,意为较多的和较少的氧原子。 Formula Name NO3- AsO43- NO2- AsO33- SO42- PO43- SO32- PO33- HSO4- HSO3- nitrate arsenate nitrite arsenite sulphate phosphate sulphite phosphite hydrogen sulphate hydrogen sulphite
16
Some Common Negative Ions --- Polyatomic Negative Ions(多原子阴离子)
In cases where it is necessary to denote more than two oxyanions of the same element, the prefixes hypo- and per-, meaning still fewer and still more oxygen atoms, respectively, may be used. 当同一元素有两种以上的含氧阴离子时,就要使用前缀hypo-(次)和per-(高), 意为更少和更多的氧原子。 Formula Name ClO- ClO3- ClO2- ClO4- hypochlorite chlorate perchlorate chlorite 还有其它一些价态固定的多原子阴离子,如: hydrogen carbonate, HCO3-; carbonate, CO32- ; acetate, OAc-等。
17
Names of Some Metal Oxides, Bases and Salts
Note: 当同一金属元素有两种以上的价态时,要使用不同的后缀,用-ous表示低价态,用-ic表示高价态。 Formula Name FeO iron(II) oxide Fe2O3 iron(III) oxide Sn(OH)2 tin(II) hydroxide Sn(OH)4 tin(IV) hydroxide Hg2SO4 mercury(I) sulphate HgSO4 mercury(II) sulphate ferrous oxide ferric oxide stannous hydroxide stannic hydroxide mercurous sulphate mercuric sulphate
18
Naming Nonmetal Oxides(非金属氧化物)
命名方法:非氧元素名称 + 氧化物(oxide)。化合物中氧原子和其它元素数目用希腊前缀来表示。这些前缀是(1) mono-, 有时可简写为mon-, (2) di-, (3)tri-, (4) tetra-, (5) penta-, (6) hexa-,(7) hepta-,(8) octa-,(9) nona- 和(10)deca-。 一般来说,当命名非金属氧化物时,这些前缀中的字母a常被省略[从(4)tetra- 起],并且mono-的字母o也经常被省略掉。

Some Common Negative Ions
Negative ions, anions, may be monatomic or polyatomic. All monatomic anions have names ending with -ide. Two polyatomic anions which also have names ending with -ide are the hydroxide, OH-, and the cyanide, CN-. 负离子,即阴离子,既可以是单原子的,也可以是多原子的。所有单原子阴离子的名字都是以-ide结尾的。两个以-ide结尾的多原子阴离子是氢氧根OH-和氰根CN-。

Binary Acids A binary compound consists of two elements. Binary acids have the prefix hydro in front of the full name of the nonmetallic element. They have the ending -ic. Examples include hydrochloric and hydrofluoric acid.
30
Hydrofluoric Acid - HF Hydrochloric Acid - HCl
Hydrobromic Acid - HBr Hydroiodic Acid - HI Hydrosulfuric Acid - H2S
31
Ternary Acids Ternary acids commonly contain hydrogen, a nonmetal, and oxygen. The name of the most common form of the acid consists of the nonmetal root name with the -ic ending. The acid containing one less oxygen atom than the most common form is designated by the -ous ending. An acid containing one less oxygen atom than the -ous acid has the prefix hypo- and the -ous ending. The acid containing one more oxygen than the most common acid has the per- prefix and the -ic ending.
