GCSE/GCSE Chemistry: Covalent Bonding PPT

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
