Ionic and Covalent Bonding Science 10 Valence e- what do we know… Which group on the periodic table, do you notice, always has all it’s valence electron shell full? The Noble Gases. This is very significant… Why?? Because every element wants to have a full outer shell of valence e...
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 Crystalline structure i.e. Crystal lattice structure the rigid arrangement of ions Solution animation What happens when only non-metal elements are involved? . . . . . . . . COVALENT BONDING
Ionic and covalent bonding animation 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 ...
