This PowerPoint presentation goes through the basics of covalent bonding and is suitable for GCSE and IGCSE Level students. Covalent bonding is described as the sharing of electrons between non-metal atoms, and care is taken to deliver the material in a paced, step-by-step fashion. This PPT assumes some knowledge of ionic bonding, so if you haven’t covered that topic yet, then you might want to delete those slides after download. Dot-and-cross diagrams are included: both with inner shells and simplified (only outer shells) formats - perfect for training students to be efficient in the exam. Activities included (feel free to edit or modify after download): Comparing bonding diagrams as a starter (spotting similarities and differences) Main teaching content (beginning from first principles with simple atomic structure, leading into covalent bond formation) Think map to compare ionic and covalent bonding (feel free to remove if needed) Drawing dot-and-cross and stick diagrams as a plenary ***Learning outcomes are included, so this is a great ‘box ticker’ for an observation lesson. *** Some syllabus references that this PPT satisfies (to name but a few): AQA GCSE Chemistry: **4.2.1.1 Chemical Trends:**Covalent bonding occurs in most non-metallic elements and in compounds of non-metals. 4.2.1.4 Covalent Bonding: When atoms share pairs of electrons, they form covalent bonds. These bonds between atoms are strong 4.2.1.4 Covalent Bonding: The covalent bonds in molecules and giant structures can be represented in the following forms (dot and cross and ball and stick examples given in the specification) **Edexcel IGCSE Chemistry: ** 1.44: Know that a covalent bond is formed between atoms by the sharing of a pair of electrons 1.45: Understand covalent bonds in terms of electrostatic attractions 1.46: Understand how to use dot-and-cross diagrams to represent covalent bonds

The resource is ideal for GCSE or IGCSE students, and is designed to act as a fun way for the students to do the following: 1. Learn how to describe each part of their timetable (e.g. "On Monday lesson 1 I have Science") 2. Learn how to ask which lesson their partner has. For example, learning how to say “which lessons do you have on a Thursday?” Both students in the role play are given a timetable, with some blank spaces missing. Each student must describe their timetable to their partner, and fill in the blank spaces. Syllabus references: CIE IGCSE German: Area A2 (School routine). Edexcel GCSE German: Section One (High Frequency Language): Numbers, Time experessions, Times of the day; Days of the week Section Two (Topic Specific Language): Daily life. What school is like.

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.
