一、元素和单质的命名“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。
1主族元素和单质：Fe : iron Mn : manganese Cu: copper Zn: zinc Hg: mercury Ag: silver Au: gold二化合物的命名：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：mono- di - tri- tetra - penta- hexa- hepta- octa-，nona-, deca-,但是在不会引起歧义时，这些前缀都尽可能被省去。
1．化合物正电荷部分的读法：直呼其名，即读其元素名称。
如CO: carbon monoxide Al2O3: aluminium oxideN2O4：Di nitrogen tetroxide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。
如FeO: iron(II) oxide 或ferrous oxide Fe2O3: iron (III)oxide或ferric oxideCu2O: copper(I) oxide 或cuprous oxide CuO: copper(II) oxide或cupricoxide２．化合物负电荷部分的读法：２．１二元化合物：常见的二元化合物有卤化物，氧化物，硫化物，氮化物，磷化物，碳化物，金属氢化物等，命名时需要使用后缀-ide，如：fluoride， chloride， bromide， iodide， oxide ，sulfide ，nitride, phosphide, carbide，hydride; OH -的名称也是用后缀-ide：hydroxide，非金属氢化物不用此后缀，而是将其看成其它二元化合物（见２。
２）；非最低价的二元化合物还要加前缀，如O22-: peroxide O2- : superoxide举例：NaF: sodium fluoride AlCl3: aluminium chlorideMg2N3 : magnesium nitride Ag2S： silver sulfideCaC2: calcium carbide Fe(OH)2：iron(II) hydroxide有些物质常用俗称，如NO nitric oxide N2O nitrous oxide２．２非金属氢化物除了水和氨气使用俗称water，ammonia以外，其它的非金属氢化物都用系统名称，命名规则根据化学式的写法不同而有所不同。
对于卤族和氧族氢化物，Ｈ在化学式中写在前面，因此将其看成另一元素的二元化合物。
举例： HF hydrogen fluoride HCl hydrogen chlorideHBr hydrogen bromide HI hydrogen iodideH2S hydrogen sulfide H2Se hydrogen selenideH2Te hydrogen telluride对于其它族的非金属氢化物，Ｈ在化学式中写在后面，可加后缀—ane，氮族还可加-ine 举例： PH3: phosphine或phosphane AsH3: arsine或arsaneSbH3: stibine或stibane BiH3: bismuthaneCH4: methane SiH4: silane B2H6: diborane２．３无氧酸命名规则：hydro-词根-ic acid举例： HCl: hydrochloric acidH2S : hydrosulfuric acid２．４含氧酸与含氧酸根阴离子化学专业英语用前后缀的不同组合显示不同价态的含氧酸和含氧酸根阴离子，价态相同的含氧酸及含氧酸根阴离子具有相同的前缀，不同的后缀。
高某酸per-ic 正酸–ic 亚酸-ous 次酸 hypo-ous高某酸根per-ate 正酸根–ate 亚酸根-ite 次酸根hypo-ite其它的前缀还有ortho-正 meta- 偏 thio-硫代举例：HClO4 perchloric acid ClO4- perchlorate ionHClO3 chloric acid ClO3- chlorate ionHClO2 chlorous acid ClO2- chlorite ionHClO hypochlorous acid ClO- hypochlorite ionH2SO4 sulfuric acid H2SO3 sulfurous acidHNO3 nitric acid HNO2 nitrous acidHPO3 metaphosphoric acid S2O32- thiosulfate ion２．５盐正盐：根据化学式从左往右分别读出阳离子和阴离子的名称。
如FeSO4 iron(II) sulfate KMnO4 potassium permanganate酸式盐：同正盐的读法，酸根中的Ｈ读做hydrogen，氢原子的个数用前缀表示。
如NaHCO3: sodium hydrogen carbonate 或 sodium bicarbonate NaH2PO4: sodium dihydrogenphosphate复盐：同正盐的读法，并且阳离子按英文名称的第一个字母顺序读。
如 KNaCO3: potassium sodium carbonateNaNH4HPO4: ammonium sodium hydrogen phosphate水合盐：结晶水读做water或hydrate如AlCl3.6H2O: aluminum chloride 6-water或 aluminum chloride hexahydrate AlK(SO4) 212H2O aluminium potassium sulphate 12-water三物理性质（physical properties）colour: colorless, red-brown, violet-black, purple-black, pale yellow, dark brownsmell: odorless, pungent, penetrating, offensive, choking, bitter, sour, sweetstate: solid, liquid, gas, gaseous, oily, crystalline, uncrystalline, molten, fusedsolubility: soluble, insoluble, slightly soluble, very soluble ,density: heavy, light , less dense, denser, greatly denser, slightly denser, about the same densehardness: hard, soft , ductile, malleabletoxicity: toxic, poisonousmelting point, boiling point: high, lowconductiv ity: electrical conductivity ; thermal conductivity ; conductor ;insulator; semiconductor四化学性质 (chemical properties)stability: stable , unstable, reactive, unreactiveredox property: oxidizing ability, reducing ability, oxidizing agent(oxidant), reducing agent (reductant), oxidation, reduction, oxidation state, valence, strong, weakacid-base property: acidic, basic, strong, weak, monohydroxy base, monoprotic acid,五化学方程式（Chemical Equations）1 反应名称：Combination；decomposition；single displacement；double displacement；redox reaction；nonredox reaction；disproportionation；neutralization；exothermic reaction; endothermic reaction; reversible reaction; forward reaction; reverse reaction; spontaneous reaction; nonspontaneous reaction2 反应条件：heat; burn; ignite/ignition ; electrolyze/electrolysis; under/at ambient/room temperature; under standard pressure; with/in the presence of a catalyst3 读法：3.1 Nitrogen reacts with hydrogen to form ammonia at high temperature and pressure with the presence of a catalyst.1 mol nitrogen reacts with 3 mol hydrogen to form2 mol ammonia at high temperature and pressure with the presence of a catalyst.3.2 Nitrogen combines with hydrogen to form ammonia at high temperature andpressure with the presence of a catalyst.Ammonia decomposes to nitrogen and hydrogen at high temperature and pressurewith the presence of a catalyst.3.3 Reaction between nitrogen and hydrogen at high temperature and pressure withthe presence of a catalyst gives ammonia.At high temperature and pressure, reaction of nitrogen with hydrogen in the presence of a catalyst takes place.六化学计算 (Chemical Calculation)1 化学术语：atomic mass/weight ; molecular weight; amount (of substance); mole; number of moles; molar mass; molar volume; concentration; molarity ; excess agent; limiting agent；reactant; product; yield;2 数学术语：＋－×÷运算名称addition subtraction mulplication division动词读法add substract(ed)·from multiply(ied)·by divide(d)·by介词读法plus minus times over运算结果sum difference product quotient0.001 o/zero point o o one2/3 two thirds＝ equals/is equal to≈ is approximately equal to＜ less than＞ greater thanx2 x squared ; x3 x cubed ; x-10 x to the minus tenth power100o c one hundred degrees centigrade5% five percent (by mass, volume)（）round brackets/parentheses[ ] square/angular brackets{} braceslinear planar trigonal square tetrahedral七化学实验（Chemical Experiments ）1 实验用品( equipments / apparatus )烧瓶 round-bottom/Florence flask 锥形瓶(conical) Erlenmeyer flask 三角漏斗funnel 长颈漏斗thistle tube 试管架test-tube rack集气瓶bottle ; glass jar 滴定管burette 烧杯beaker玻棒glass rod 洗瓶wash bottle 干燥管drying tube试管刷 test tube brush 温度计thermometer 火柴 match酒精灯 burner 石棉网 wire gauze 铁架台 iron stand指示剂 indicator 酚酞phenolphthalein U型管U tube石蕊litmus 甲基橙methyl orange 淀粉starch橡皮塞 rubber stopper 橡皮管 rubber tube 滴管 eye dropper角匙 spoon 蒸发皿evaporation dish 滤纸 filter paper 研,棒mortar and pestle 量筒graduated cylinder 天平 balance2 实验报告:aims ; principles/introduction ; procedures ; observations; conclusion/deduction brisk effervescence, precipitate, milky, aqueous solution3实验类型：confirmative test ; inquiry test; qualitative analysis; quantitative analysis ;measurement / determination on4实验操作：collect gas （over water; upward displacement of air; downward delivery）bubble gas through ; dry gas ; suck bac如有侵权请联系告知删除，感谢你们的配合！。
