所谓的bonding(键)其实就是一种连接方式,需要学习的是atom原子这样的微观粒子,通过何种方式连接成为我们眼中能看到的宏观的物质。 今天我们来讲一下三种不同的bonding---ionic 、covalent、metallic Ionic bonding(离子键):原子在得失电子后成为ion(离子),失去电子的原子成为positive ions(其整体带正电,因内部带正电...
Chemical Bonding Ionic and Covalent Compounds Chapters 8-9KO
Covalent and ionic bonds have different bonding strengths. Adding energy–heat in most cases–will show those differences within just a few minutes. Take a known covalently bonded compound and heat it. The compound should melt after only a few minutes. Provide an ionic compound and heat it. T...
This chapter covers chemical bonding between atoms and ions and how this affects the chemical properties of the elements. Which elements form ions and the typical charges on the ions are explained. Ionic bonding and covalent bonding are compared in terms of the octet rule and valence bond theory...
There are three types of chemical bonds: ionic bonding, covalent bonding and metallic bonding. This quiz will focus on covalent bonding. Use your knowledge of atoms and covalent bonding to answer the following questions.Group: Chemistry Chemistry Quizzes ...
