IONIC BONDING Some elements tend to gain electron(s) readily while others tend to lose electron(s) (low I.E.) When an active element (metal) reacts with an active non-metal), electrons are transferred from the metal to the non-metal. Atoms of the non-metal become anions while the met...

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....
Covalent bonding(共价键):当原子间的电负性较为接近时,多个原子共同使用它们的最外层电子,列如A原子提供一个电子,B原子提供另一个电子,这两个电子形成共享电子对(shared pairs),剩余的未参加共享的电子对我们叫做lone pairs(孤对电子),shared pairs就像一个桥梁,A的原子核和它存在静电吸引力,B的原子核同样和它存...
