Unit 3 Lesson 4 Ionic, Covalent, and Metallic Bonding How does an ionic bond form? • An ionic bond is a force that brings oppositely charged ions together. • Ionic bonds form when electrons are transferred from a metal atom to a nonmetal atom....
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...

Ionic bonding formed when one atom has sufficient strength of attraction to remove ion from the other atom. Covalent bonding occurs when neither atom has sufficient strength to remove the other atom's electron. They would instead share electrons to form stable configurations of electrons. ...
Metallic bonding is utilized to express the features of metals. This is because the metallic bonds contain strong atomic attraction that enables the electrons to transport electricity and other forms of energy across the metals. Also, metallic bonding makes the metal have a high density....
