Chemistry 2A - Structure and Bonding 0.0 / 5 ? ChemistryStructure and bondingGCSEAQA Created by: Maddie A-PCreated on: 20-03-15 21:17 Describe the process of ionic bonding. When atoms lose or gain electrons to form charged particles (ions) which are then strongly attracted to one another (opposite charges attract) 1 of 5 Describe the electronic structure of sodium. 2,8,1 2 of 5 What is covalent bonding? Where atoms share electrons with each other so that they've got full outer shells 3 of 5 What are the two types of covalent substance? Give three examples of each. Simple Molecular Substances - Chlorine, oxygen and water Giant Covalent Structures - Diamond, graphite and silicon dioxide 4 of 5 List three properties of metals and explain how metallic bonding causes these properties. They consist of a giant structure. They have a 'sea of delocalised electrons'. The free electrons allow the layers of atoms to slide over each other. 5 of 5
