化学高考选修三大题及解析_化学高考选修3

(1)5s 2 5p 2 (2分)

(2)?图略 (2分) sp 3 、 、 sp 2 (各1分)

(3)正四面体;SnCl 4 (各1分)

(4)SnO 2 (2分)

(5)配位数大,空间利用率大(2分)

(6)952/N A (a×10 —10 ) 3 (3分)

试题分析:(1)Sn元素是50号元素,最外层电子是4个,位于元素周期表的第五周期,第四主族,所以价层电子排布式为5s 2 5p 2 ;

(2)Sn元素的5p轨道上有空轨道,Cl原子中有孤对电子,所以1个SnCl 2 分子中的Sn与另一分子中的Cl原子可以形成配位键,从而形成一维链状聚合结构,配位键的形式是从提供孤对电子的一方指向提供空轨道的一方;固体分子SnCl 2 中存在一个配位键,所以Sn的价层电子对数是3+1/2(4-2×1)=4,所以是sp 3 杂化;气态时以单分子形式存在,所以Sn的价层电子对数是2+1/2(4-2×1)=3, sp 2 杂化;

(3)SnCl 4 分子中Sn的价层电子对数是4+1/2(4-4×1)=4,空间构型是正四面体型;SnCl 4 与CCl 4 都是分子晶体,所以相对分子质量大的分子间作用力大,沸点较高,所以SnCl 4 的沸点较高;

(4)锡的某种氧化物的晶胞中Sn原子8顶点各1个和中心1个,共是8×1/8+1=2个,O原子分别在上下2个底面各2个和体内的2个,共是4×1/2+2=4,所以Sn与O的原子个数比是2:4=1:2,化学式为SnO 2

(5)白锡的晶体结构中Sn原子的配位数为4和6,灰锡的晶体结构与金刚石的晶体结构相似,配位数是4,所以白锡晶体的配位数大,空间利用率大,单位体积拥有的Sn原子多,密度大;

(6)灰锡晶胞中Sn原子的个数是8,与金刚石晶胞中C原子个数相同,所以灰锡的密度=m/V=8×119/N A /(a×10 -10 ) 3 =952/N A (a×10 —10 ) 3 g/cm 3

化学一选修3物质结构与性质N和B元素在化学中有很重要的地位.(1)写出与N元素同主族的As元素的基态

A、B、C、D、E为短周期主族元素,F、G为第四周期元素,它们的原子序数依次增大,A元素的核外电子数和电子层数相等,也是宇宙中最丰富的元素,为H元素;

B元素原子的核外p电子数比s电子数少1,且B是短周期元素,如果B是第三周期元素,则不可能出现p电子比s电子少1,则B为第二周期元素,为N元素;

C的原子序数大于B且为短周期元素,根据C的电离能知,C属于第ⅢA族元素,为Al元素;

D原子核外所有p轨道全满或半满且为短周期主族元素,原子序数大于C,则D是P元素;

E元素的主族序数与周期数的差为4,且E为短周期主族元素,E的原子序数大于D,则E是Cl元素;

F是前四周期中电负性最小的元素,即为最活泼的金属元素,为K元素;

G在周期表的第七列,且为第四周期元素为Mn元素,

(1)G为Mn元素,是25号元素,位于第四周期第ⅦB族,最后填充的为d电子,为d区元素,价电子排布式为3d 5 4s 2 ,

故答案为:ⅦB;d;3d 5 4s 2 ;

(2)B为N元素,核外电子排布式为1s 2 ns 2 np 3 ,基态原子中能量最高的电子,处于2p能级,有3个电子,其电子云在空间有3个方向,原子轨道呈纺锤或哑铃形,

故答案为:3;纺锤或哑铃形;

(3)C是Al元素,根据构造原理知,其原子核外电子排布图为: ,

故答案为: ;

(4)NH 5 为离子化合物,是由NH 4 + 与H - 两种粒构成,电子式为 ,

故答案为: ;

(5)PCl 3 中心原子P原子成3个σ键,P原子价层电子对是为3+1=4,含有1对孤对电子对,杂化轨道数为4,杂化方式为sp 3 ,其空间构型为三角锥,

故答案为:sp 3 ;三角锥;

(6)钾原子和氯原子通过得失电子形成离子键,用电子式表示其形成过程为: ,

故答案为: .

四川高考理科生需要学化学选修三吗

(1)N元素属于第VA族元素,则As是第VA族元素,其最外层s能级、p能级上分别含有2、3个电子,As是33号元素,其原子核外有33个电子,根据构造原理知其基态原子核外电子排布式为:1s22s22p63d104s24p3或[Ar]3d104s24p3,

同一周期元素中,元素的第一电离能随着原子序数的增大而呈增大趋势,但第VA族元素的第一电离能大于其相邻元素,所以三种元素的第一电离能由大到小的顺序为N>O>B,

故答案为:1s22s22p63d104s24p3或[Ar]3d104s24p3;N>O>B;

(2)N元素与B元素的氟化物化学式相似,均为AB3型,但N元素的氟化物中氮原子含有孤电子对,B元素的氟化物中B元素不含孤电子对,所以N原子和B原子采用的杂化方式不同,导致其空间构型不同;BF3中B原子含有3个σ键且不含孤电子对,所以BF3为平面三角形构型,

故答案为:N原子和B原子采用不同的杂化方式;平面三角形;

(3)BN的硬度较大,所以BN是原子晶体,根据金刚石的结构知BN中B原子的杂化方式为sp3,原子晶体中只含有共价键,故答案为:sp3;共价键;

(4)①3mol?NaN3受撞击会生成4mol?N2气体和一种离子化合物A,根据原子守恒确定离子化合物A的化学式为Na3N,根据反应物、生成物知,

该反应方程式为:3?NaN3=4N2+Na3N,

故答案为:3?NaN3=4N2+Na3N;

②共价单键为σ,共价三键中含有一个σ键和2个π键,氮气分子的结构式为N≡N,所以一个氮气分子中含有1个σ键和2个π键,则N2分子中存在的σ键和π键数目之比为1:2,故答案为:1:2.

高中化学选修几门

基本是不学的,在四川基本大多数的高中都不会选择去学化学,选修三这样子的一本书,因为化学选修三这样子的一本书所涉及到的物质结构与性质,这样子的一个知识点的话基本不会出现在高考题里面。

所以老师是会选择去放弃这本书,而去讲其他一些重要的知识点所在的教材里面的。必修的书的话,基本全部都会去讲到,然后在选修的书里面主要就是讲那些有涉及到高考题的教材。

如果是没有涉及到的话会直接放弃,或者让学生自己去自学等等,所以最后的结论就是四川高考理科生基本是不学化学选修三的。

[化学一选修3:物质结构与性质]一水硫酸四氨合铜(Ⅱ)(化学式为[Cu(NH3)4SO4?H2O]是一种重要的染料及

选修五本:

选修1:化学与生活。

选修2:化学与技术。

选修3:物质结构与性质。

选修4:化学反应原理。

选修5:有机化学基础。

选修6:实验化学。

目前的高中化学教材分为两部分:必修和选修。

必修顾名思义就是必须学的(不管是文科生还是理科生,高一都要学习化学的必修教材),共有两本,必修一和必修二。内容如下:

必修一:化学实验相关、物质的量相关、物质分类法、离子反应和氧化还原反应、金属非金属性质和元素化学。元素化学主要讲了钠、铝、铁等金属和氯、硫、硅、氮等非金属相关的化学知(fan)识(ying),但考试考的绝不止这些。

必修二:部分元素周期表和一点点元素周期律、极其基础的化学键相关知识、极其基础的化学反应原理,包括化学热力学(能量变化)、电化学(原电池)和化学动力学(反应速率)、极其基础的有机化学(很散不好怎么概括)、资源开发利用。

这本书emmmm,不好怎么说,它几乎什么都讲了一点,但什么都讲得不深,又讲得很散,被选修吊着打……也许就只是一本为选修服务的基础入门书吧。(很多工具书甚至把必修二和选修四放在一起讲)。

必修部分共两本,看似内容很多但全是基础,基础打得牢的人学起来基本无压力。

高中化学有没有必修3

孔雀石(主要成分为Cu2(OH)2CO3,含少量Fe2O3和SiO2杂质)和稀硫酸反应生成硫酸铜、二氧化碳、硫酸铁,二氧化硅不溶于稀硫酸,所以A是二氧化硅,B中含有硫酸铁、硫酸铜,C是二氧化碳,B中加入氧化铜调节溶液的pH生成氢氧化铁,则溶液中存在硫酸铜,

(1)二氧化硅晶体结构中,每个硅原子结合4个氧原子原子,同时每个氧原子结合2个硅原子原子,最小的环上,有6个Si原子和6个O原子,所以一共12个原子;二氧化碳分子中含有2个σ键和2个π键,所以σ键和π键个数比为1:1,

故答案为:12;1:1;

(2)溶液D的溶质阴离子为硫酸根离子,SO42-中价层电子对个数,4+

2
(6+2-4×2)=4,所以为正四面体结构,中心原子采用?sp3?杂化,

故答案为:正四面体;sp3;

(3)离子晶体的熔点与晶格能成正比,晶格能与电荷成正比,与离子半径成反比,氧化镁的中镁离子直径小于铜离子,所以氧化镁的晶格能大于氧化铜,则氧化镁的熔点高,

故答案为:MgO的晶格能大;

(4)一水硫酸四氨合铜(Ⅱ)中配离子([Cu(NH3)4]2+)中铜原子和氮原子形成4个配位键,其配位键表示为,

故答案为:;

高中化学没有必修三。

高中化学分为必修和选修。必修包含必修一和必修二。选修包含、化学与生活选修1、化学与技术选修2、物质结构与性质选修3、化学反应原理选修4、有机化学基础选修5、实验化学选修6。必修两本是必须要学的,高考时都会考到的。

选修可以选两本自己想学的或者自己擅长的,一般学校老师会挑选两到三门选修进行学习。

高中化学选修专题高中化学选修3内容为物质结构与性质,在学习选修三时可以参考教辅书来学习。

扩展资料:

高考化学必考内容:必考内容涵盖必修模块“化学一”和“化学二”和选修模块“化学反应原理”的内容。根据化学学科的学科体系和学科特点,必考内容的部分包括:化学学科特点和基本研究方法、化学基本概念和基本理论、常见无机物及其应用、常见有机物及其应用和化学实验基础五个方面。
