英文大人进～
1.How is it possible to predict if a bond is ionic or covalent?What types of atoms generally form ionic or covalent bonds?How can electronegativities be used to determine the type of bond?(8 points)
2.Draw Lewis dot structures of the diatomic molecules 02 and N2.How many valence electrons does each atom have,and how does that affect the type of bond formed in each molecule?Why do nitrogen molecules have a bond order of three,whereas oxygen molecules have a bond order of two?(12 points)
3.What determines the electron-group geometry of a molecule?What determines the molecular geometry of a molecule?Why can-electron group geometry differ from molecular geometry?Use a Lewis dot diagram of any molecule to help in your explanation.(10 points)
4.What is the oxidation state of Mg in MgO?How do you know?(6 points)
5.Differentiate between the names of CCl4 and C4H8.What is used to describe the number of each type of atom in each molecule?Explain your reasoning.(6 points)
6.What is the difference between a polar bond and a polar molecule?Use water as an example to help in your explanation.Explain how water has polar bonds and is also a polar molecule.(8 points)
请用英文回答下列问题～

首先同学,这些化学题跟你讲解可以,可是你里面还有画图,我怎么画给你啊
这些是基础题目,不知道你是哪个年级的,如果你是在上大学的基础化学课的话,学校有tutor.俺都是去年学的东西了,你倒不如说说有那些不懂的,我再回答吧,因为这些不是单纯英文题目啊,而是英文化学题目,你可以先自己看看,有哪里不懂的再问吧
1.ionic 是金属与非金属,covalent是两个都是非金属
ionic的electronegativities高于covalent
2.图要你自己画,我就没办法讲了,种类书里面应该有一个表可以查,我这些忘了
3.两个的不同点在于一种单独电子有参加,名称 electron geometry d tetrahedral 包含molecular geometry的 tetrahedral,trigonal pyramidal he bent,molecular单独电子是决定因素之一
能回答的就这么多了,这简直就是一份试卷嘛,我当时化学考试的时候还没有这么多问答题呢~!!!
