01 THE ELEMENTS AND THE PERIODIC TABLE 01 元素和元素周期表 The number of protons in the nucleus of an atom is referred to as the atomic number, or proton number, Z. The number of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom is determined very nearly by the total number of protons and neutrons in its nucleus. This total is called the mass number, A. The number of neutrons in an atom, the neutron number, is given by the quantity A-Z. 质子的数量在一个原子的核被称为原子序数,或质子数、周淑金、电子的数量在一个电中性原子也等于原子序数松山机场的总质量的原子做出很近的总数的质子和中子在它的核心。这个总数被称为大量胡逸舟、中子的数量在一个原子,中子数,给出了a - z的数量。 The term element refers to, a pure substance with atoms all of a single kind. T o the chemist the "kind" of atom is specified by its atomic number, since this is the property that determines its chemical behavior. At present all the atoms from Z = 1 to Z = 107 are known; there are 107 chemical elements. Each chemical element has been given a name and a distinctive symbol. For most elements the symbol is simply the abbreviated form of the English name consisting of one or two letters, for example: 这个术语是指元素,一个纯物质与原子组成一个单一的善良。在药房“客气”原子的原子数来确定它,因为它的性质是决定其化学行为。目前所有原子和Z = 1 a到Z = 107是知道的;有107种化学元素。每一种化学元素起了一个名字和独特的象征。对于大多数元素都仅仅是一个象征的英文名称缩写形式,一个或两个字母组成,例如: oxygen==O nitrogen == N neon==Ne magnesium == Mg
1 Unit5元素周期表 As our picture of the atom becomes more detailed 随着我们对原子的描述越来越详尽，我们发现我们陷入了进退两难之境。有超过100多中元素要处理，我们怎么能记的住所有的信息？有一种方法就是使用元素周期表。这个周期表包含元素的所有信息。它记录了元素中所含的质子数和电子数，它能让我们算出大多数元素的同位素的中子数。它甚至有各个元素原子的电子怎么排列。最神奇的是，周期表是在人们不知道原子中存在质子、中子和电子的情况下发明的。Not long after Dalton presented his model for atom( )在道尔顿提出他的原子模型（原子是是一个不可分割的粒子，其质量决定了它的身份）不久，化学家门开始根据原子的质量将原子列表。在制定像这些元素表时候，他们观察到在元素中的格局分布。例如，人们可以清楚的看到在具体间隔的元素有着相似的性质。在当时知道的大约60种元素中，第二个和第九个表现出相似的性质，第三个和第十个，第四个和第十一个等都具有相似的性质。 In 1869,Dmitri Ivanovich Mendeleev,a Russian chemist, 在1869年，Dmitri Ivanovich Mendeleev ,一个俄罗斯的化学家，发表了他的元素周期表。Mendeleev通过考虑原子重量和元素的某些特性的周期性准备了他的周期表。这些元素的排列顺序先是按原子质量的增加,,一些情况中, Mendeleev把稍微重写的元素放在轻的那个前面.他这样做只是为了同一列中的元素能具有相似的性质.例如,他把碲(原子质量为128)防在碘(原子质量为127)前面因为碲性质上和硫磺和硒相似, 而碘和氯和溴相似. Mendeleev left a number of gaps in his table.Instead of Mendeleev在他的周期表中留下了一些空白。他非但没有将那些空白看成是缺憾，反而大胆的预测还存在着仍未被发现的元素。更进一步，他甚至预测出那些一些缺失元素的性质出来。在接下来的几年里，随着新元素的发现，里面的许多空格都被填满。这些性质也和Mendeleev所预测的极为接近。这巨大创新的预计值导致了Mendeleev的周期表为人们所接受。 It is known that properties of an element depend mainly on the number of electrons in the outermost energy level of the atoms of the element. 我们现在所知道的元素的性质主要取决于元素原子最外层能量能级的电子数。钠原子最外层能量能级（第三层）有一个电子，锂原子最外层能量能级（第二层）有一个电子。钠和锂的化学性质相似。氦原子和氖原子外层能级上是满的，这两种都是惰性气体，也就是他们不容易进行化学反应。很明显，有着相同电子结构（电子分布）的元素的不仅有着相似的化学性质，而且某些结构也表现比其他元素稳定（不那么活泼） In Mendeleev’s table,the elements were arranged by atomic weights for 在Mendeleev的表中，元素大部分是按照原子数来排列的，这个排列揭示了化学性质的周期性。因为电子数决定元素的化学性质，电子数也应该（现在也确实）决定周期表的顺序。在现代的周期表中，元素是根据原子质量来排列的。记住，这个数字表示了在元素的中性原子中的质子数和电子数。现在的周期表是按照原子数的递增排列，Mendeleev的周期表是按照原子质量的递增排列，彼此平行是由于原子量的增加。只有在一些情况下（Mendeleev注释的那样）重量和顺序不符合。因为原子质量是质子和中子质量的加和，故原子量并不完全随原子序数的增加而增加。原子序数低的原子的中子数有可能比原子序数高的原

Unit 1 Chemical Industry 化学工业 1.Origins of the Chemical Industry Although the use of chemicals dates back to the ancient civilizations, the evolution of what we know as the modern chemical industry started much more recently. It may be considered to have begun during the Industrial Revolution, about 1800, and developed to provide chemicals roe use by other industries. Examples are alkali for soapmaking, bleaching powder for cotton, and silica and sodium carbonate for glassmaking. It will be noted that these are all inorganic chemicals. The organic chemicals industry started in the 1860s with the exploitation of William Henry Perkin‘s discovery if the first synthetic dyestuff—mauve. At the start of the twentieth century the emphasis on research on the applied aspects of chemistry in Germany had paid off handsomely, and by 1914 had resulted in the German chemical industry having 75% of the world market in chemicals. This was based on the discovery of new dyestuffs plus the development of both the contact process for sulphuric acid and the Haber process for ammonia. The later required a major technological breakthrough that of being able to carry out chemical reactions under conditions of very high pressure for the first time. The experience gained with this was to stand Germany in good stead, particularly with the rapidly increased demand for nitrogen-based compounds (ammonium salts for fertilizers and nitric acid for explosives manufacture) with the outbreak of world warⅠin 1914. This initiated profound changes which continued during the inter-war years (1918-1939). 1．化学工业的起源 尽管化学品的使用可以追溯到古代文明时代，我们所谓的现代化学工业的发展却是非常近代（才开始的）。可以认为它起源于工业革命其间，大约在1800年，并发展成为为其它工业部门提供化学原料的产业。比如制肥皂所用的碱，棉布生产所用的漂白粉，玻璃制造业所用的硅及Na2CO3. 我们会注意到所有这些都是无机物。有机化学工业的开始是在十九世纪六十年代以William Henry Perkin 发现第一种合成染料—苯胺紫并加以开发利用为标志的。20世纪初，德国花费大量资金用于实用化学方面的重点研究，到1914年，德国的化学工业在世界化学产品市场上占有75%的份额。这要归因于新染料的发现以及硫酸的接触法生产和氨的哈伯生产工艺的发展。而后者需要较大的技术突破使得化学反应第一次可以在非常高的压力条件下进行。这方面所取得的成绩对德国很有帮助。特别是由于1914年第一次世界大仗的爆发，对以氮为基础的化合物的需求飞速增长。这种深刻的改变一直持续到战后（1918-1939）。 date bake to/from: 回溯到 dated: 过时的，陈旧的 stand sb. in good stead: 对。。。很有帮助

仅供参考 Introduction to Organic Chemistry 1. Sources of Organic Compounds The major sources of organic chemicals are coal, petroleum, and agricultural products. Both coal and petroleum were formed through the geologic processes of changing animal and plant remains into carbon-containing residues. About one-third of all organic chemicals are derived from coal and about one-half from the petroleum industry 有机化合物的来源 有机化学药品的主要来源是煤、石油和农产品。动植物的遗体通过地质作用变成含碳残基然后形成煤和石油。三分之一的所有有机化合物品是从煤中得到的，一般来自于石油工业。 2. The Methods and Objectives of Organic Chemistry Because of the tremendous number of organic compounds known, and of the many more being synthesized daily, the study of organic chemistry is not the study of individual compounds, it is the study of groups or families of compounds all closely related to each other. Obviously, the former approach would be prohibitive[prE5hibitiv]. Once the structural relationships of certain typical members of a particular group or family of compounds are understood, these structural features are understood for any one of the many members of the family, even though some may not be known compounds. 因为已知的有机化合物的数目庞大，而且还在逐日合成更多的品种，所以有机化学不是研究单个的化合物，而是把彼此密切相关的化合物按类或族来研究。显然，以前的方法是不可取的，一旦典型的一类特殊化合物被认识，这些结构特征将适用于这类化合物，甚至是一些未知的化合物， For each group or family of compounds often called homologous series of compounds, structural features are important. In studying organic chemistry, it is not enough to know the identities of the elements and how many atoms of each element are present in a given molecule. More importantly, the order in which these atoms are linked together to form
Unit10 Nomenclature of Hydrocarbons碳氢化合物的命名 Alkanes烷烃 理想的，每一种化合物都应该由一个明确描述它的结构的名称，并且通过这一名称能够画出它的结构式。为了这一目的，全世界的化学家接受了世界纯粹与应用化学会（IUPAC）建立的一系列规则。这个系统就是IUPAC系统，或称为日内瓦系统，因为IUPAC的第一次会议是在瑞士日内瓦召开的。不含支链的烷烃的IUPAC命名包括两部分（1）表明链中碳原子数目的前缀；（2）后缀－ane，表明化合物是烷烃。用于表示1至20个碳原子的前缀见表 表中前4个前缀是由IUPAC选择的，因为它们早已在有机化学中确定了。实际上，它们甚至早在它们成为规则之下的结构理论的暗示之前，它们的地位就确定了。例如，在丁酸中出现的前缀but－，一种表示在白脱脂中存在的四个碳原子的化合物（拉丁语butyrum白脱（黄油））。表示5个或更多碳原子的词根来源于希腊或拉丁词根。 含取代基的烷烃的IUPAC名称由母体名称和取代基名称组成，母体名称代表化合物的最长碳链，取代基名称代表连接在主链上的基团。 来源于烷烃的取代基称为烷基。字母R－被广泛用来表示烷烃的存在.烷烃的命名是去掉原烷基名称中的－ane加上后缀－yl。例如，烷基CH3CH2－称为乙基。 CH3－CH3乙烷（原碳氢化合物）CH3CH2－乙基（一个烷基） 下面是IUPAC的烷烃命名规则： 1. 饱和碳氢化合物称为烷烃。 2. 对有支链的碳氢化合物，最长的碳链作为主链，IUPAC命名按此主链命名。 3. 连接在主链上的基团称为取代基。每一取代基有一名称和一数字.这一数字表示取代基连接在主链上的碳原子的位置。 4. 如果有多于一个的相同取代基，要给出表示支链位置的每个数字。而且，表示支链数目的数字由前缀di－，tri－，tetra－，penta－等表示。 5. 如果有一个取代基，主链碳原子编号从靠近支链的一端开始，使支链位号最小。如果有两个或多个取代基，支链从能使第一个取代基位次较小的一侧编号。 6. 如果有两个或多个取代基，它们按字母顺序排列。当排列取代基时，前缀iso－（异）和neo－（新）也按字母排列，前缀sec－（仲）和tert－（特）在字母排列中忽略 此外，按字母排列取代基时，表示倍数的前缀2，3，4等也被忽略。 Alkenes烯烃 烷烃的碳原子间只有单键。烯烃在两个碳原子间有双键（两个键）。考虑到两个碳原子间以双键相连。因为双键用去了两个碳原子的共4个电子。所以只剩下4个电子以供成
