34、。模型可以是一幅图、一张表或计算机图象,也可以是一个复杂的对象或过程的示意 符号的作用:(1)、简单明了地表示事物(2)、可避免由于事物形态不同引起的混乱(3)、可避免由于表达的文字语言不同引起的混乱2、 分子 分子是构成物质,并保持物质化学性质的一种微粒。同种分子性质相同,不同种分子性质不同。扩散现象是大量分子运动的宏观表现。扩散现象证明了分子在不断地运动。温度越高,分子运动越快。酒精和水混合实验,证明:分子之间存在着间隔。分子间还存在着引力和斥力。 (1)运动(温度越高,运动越快)-扩散现象分子运动论 (2)间隔 -酒精和水混合实验(3)引力、斥力 -压缩空气时很费力(斥力)拉断一根绳子需
35、要很大力气(引力) 3、原子原子是化反应中的最小微粒,在化学反应中不可分。原子也是构成物质的一种微粒:如金属由原子直接构成,金刚石、石墨等碳的单质也有原子直接构成等等。 原子结构的初步知识 质 子 :每一个质子带一个单位的正电荷原子核 (带正电)原子 (带正电) 中 子 (不带电)(氢原子没有中子) 核外电子(带负电):每个电子带一个单位的负电荷说明:1、原子核和核外的电子所带的电荷总数相等,电性相反,整个原子不显电性。2、质子和中子又是由更小的微粒夸克构成3、核电荷数 = 质子数 = 核外电子数 相对原子质量=质子数+中子数4、原子一定有电子和质子,但不一定有中子。(H)原子结构模型的发展历
36、史:道尔顿:实心原子结构模型汤姆森:“汤姆森模型”、卢瑟福: “核式模型玻尔:“分层模型”“电子云模型”。 道尔顿最早提出原子理论;汤姆生发现电子;卢瑟福提出原子核结构。4、离子 离子:带电的原子或原子团。(可溶性盐、酸、碱) 5、同位素同位素:原子中原子核内质子数相同、中子数不相同的同类原子的统称。同位素原子与元素的关系:元素是同位素原子的总称,同位素原子是一种元素的不同原子。(氢:氕、氘、氚) 同位素的应用:核设施、文物鉴定、医学诊断等 6、元素 具有相同核电荷数(即质子数)的同一类原子总称。 元素和原子的区别和联系元素原子定义具有相同核电荷数(即质子数)的同一类原子总称为元素。化学变化中
37、的最小微粒区分只讲种类,不讲个数组成物质(单质和化合物)既讲种类,又讲个数构成分子,也直接构成物质使用描述物质的宏观组成描述物质的微观结构联系元素是原子的总称;元素的种类由原子中的核电荷数(质子数)决定 了解:(1)、地壳中元素:氧硅铝铁(2)、海水中的元素:除了水由氢和氧元素组成外,还含有氯元素、钠元素等(3)、人体中元素:含量最多的分别为碳、氢、氧、氮(介绍人体中各元素的作用) 元素种类:金属元素和非金属元素(稀有气体) 元素符号的意义:如N,可表示氮元素,也可表示一个氮原子;如是单质的其元素符号还可表示这种单质(C)。 元素周期表:在元素周期表的同一周期中,从左到右,元素原子的质子数逐渐
38、增加。在同一族内,各元素的化学性质都很相似。要知道元素周期表的一些结构和规律 7、化学式 用元素符号表示物质组成的式子,叫做化学式。化学式表示的意义:(1)、表示某种物质;(2)、表示该物质由哪些元素组成;(3)、表示组成该物质各元素的原子个数比(质量比);(4)、表示这种物质的一个分子:(5)、表示该物质由什么分子构成:(6)、表示一个分子由什么原子构成。 如:CO2:(1)表示二氧化碳(2)表示二氧化碳由氧元素和碳元素组成(3)组成二氧化碳的碳原子与氧原子的数量比为:1:2(4)表示一个二氧化碳分子(5)二氧化碳由二氧化碳分子组成(6)一个二氧化碳由一个碳原子和两个氧原子构成。单质和化合物
39、 纯净物 单 质:由同种元素组成的纯净物 例:氧气 ,金属 ,稀有气体等物质 化合物:由不同种元素组成的纯净物 例:水 ,CO2 ,所有的盐 ,酸 等混合物 :如空气、天然水、盐酸 、所有的溶液氧化物:由两种元素组成且其中一种是氧元素的化合物叫氧化物。如:CO2,CaO等。元素的存在形态:以单质形态存在的叫做元素的游离态。 如:氧气中的氧元素以化合物形态存在的叫做元素的化合态。 如:水中的氢元素和氧元素 8、化合价 A化合价有正、负之分;B在化合物里,通常金属元素显正价(氢为+1价),非金属元素显负价(氧显-2价);C在化合物里,各元素的正负化合价的代数和等于零;D在单质分子里元素的化合价为零
40、;E有些元素的化合价是可变的;F同一元素在同一化合物中化合价也可能不同(NH4NO3)。 原子团的化合价 -2 -1 +1 -2 -1 -1 -1 -2SO4 OH NH4 CO3 NO3 ClO3 MnO4 MnO4 书写原则:根据元素的化合价,写出化学式。方法:先写元素符号在其上方标出化合价利用交叉法在对应元素的右下角标出原子个数。要注意各元素原子的个数应为最简整数比!离子符号的表示:先写上元素符号,在其右上角标出所带的电荷数及其电性。如Na+ Cl 有些离子是带电的原子集团,方法与上同,将它看成一个整体即可,称为某某离子 如:铵根离子NH4碳酸根离子CO32 9、相对原子质量:国际上以C
41、12原子质量的1/12作为标准,其他原子的质量跟它相比较所得的比值,就是该种原子的相对原子质量。相对原子质量之比等于原子的实际质量之比。相对原子质量是一个比值,有单位。一般不标出。 相对分子质量等于一个分子中各原子的相对原子质量之和。 10、根据化学式的计算 1. 相对分子质量等于一个分子中各原子的相对原子质量之和。2.化合物中各元素的质量比(个数比):设化学式为x y 元素:原子个数(x)的相对原子质量;元素:原子个数(y)的相对原子质量 个数关系 个粒子 个粒子3.元素的质量分数100%100% 4.化合物中元素的质量化合物的质量元素的质量分数 5.混合物中某元素的质量混合物质量该元素在化
