WebFeb 1, 2016 · DESCRIPTION. Ionic, Covalent and Metallic Structures. IONIC. COVALENT. eg sodium chloride (salt). PURE substances have different STRUCTURES depending on the type of BONDING they have. METALLIC eg copper. SIMPLE eg carbon dioxide, water. GIANT eg diamond, graphite. - PowerPoint PPT Presentation. WebStructure and properties of metals. Metals have giant structures. Metallic bonding is strong meaning that most metals have very high melting and boiling points. The layers are able to slide over each other, which means that metals can be bent and shaped. Metals are good conductors of electricity because the delocalised electrons are able to move.
