1、商務(wù)英語(yǔ)寫(xiě)作 英文版無(wú)機(jī)物英語(yǔ)命名 Naming inorganic compounds metal containing Compounds containing a metal will be based on the name of the elemental metal plus the name of the anion. The name of simple nonmetal anions convert the ending of the element name with -ide. Polyatomic anions usually end with -ite or -ate

2、. Note that hydroxide, OH-, is an exception. F- fluoride Cl- chloride ClO2- chlorite ClO32- chlorate ClO4- perchlorate Br- bromide BrO32- bromate I- iodide IO32- iodate O2- oxide OH- hydroxide O22- peroxide S2- sulfide SO32- sulfite SO42- sulfate Se2- selenide N3- nitride NO2- nitrite NO3- nitrate P

3、3- phosphide PO43- phosphate As3- arsenide AsO32- arsenate C4- carbide CO32- carbonate Si4- silicide SiO44- silicate a few more HCO3- hydrogen carbonate bicarbonate HSO3- hydrogen sulfite bisulfite HSO4- hydrogen sulfate bisulfate HPO42- hydrogen phosphate H2PO4- dihydrogen phosphate common organic

4、anions CH3COO- acetate HCOO- formate C2O42- oxalate common anions containing metals MnO4- permanganate CrO42- chromate Cr2O72- dichromate numeral in Metals with multiple oxidation states use a Roman parentheses to specify the oxidation state. Example: formula write as read as FeCl2 ironII chloride i

5、ron two chloride FeCl3 ironIII chloride iron three chloride nonmetals The name of nonmetallic compounds use the name of the first element in the formula followed by the name for the other elements in the compound, modified as above. A prefix indicates the number of each atom in the compound. Example

6、s: formula read as CO carbon monoxide CO2 carbon dioxide SO2 sulfur dioxide SO3 sulfur trioxide N2O5 dinitrogen pentoxide Naming Complexes Complex ions are named with the ligand names added as prefixes to the name of the central metal ion. Anionic ligands are modified with the suffix -o, for example: chloro, Cl-, cyano, CN-, and hydroxo, OH-. Most neutral ligands retain their usual name, a few exceptions are: formula ligand name C=
