This PowerPoint Presentation covers most of the requirements for the Covalent Bonding unit for Edexcel IGCSE Chemistry in a clear and coherent manner. These slides may also be useful for other exam boards, such as AQA, WJEC, CIE, etc., if modified after download. Specification statements covered include: 1.31 describe the formation of a covalent bond by the sharing of a pair of electrons between two atoms. 1.32 understand covalent bonding as a strong attraction between the bonding pair of electrons and the nuclei of the atoms involved in the bond. 1.33 explain, using dot and cross diagrams, the formation of covalent compounds by electron sharing for the following substances: Hydrogen, chlorine, hydrogen chloride, water, methane, ammonia, oxygen, nitrogen, carbon dioxide, ethane, ethene. 1.34 recall that substances with simple molecular substances are gases or liquids, or solids with low melting points. 1.35 explain why substances with simple molecular structure have low melting points in terms of the relatively weak forces between the molecules. 1.36 explain the high melting points of substances with giant covalent structures in terms of the breaking of many strong covalent bonds.
