A concise lesson presentation (21 slides) which uses a range of methods to allow students to discover how to draw dot and cross diagrams for covalent structures. The lesson begins by challenging the students to recall their knowledge of electronic structure to show the outer shell of two specified atoms. They will then see how it is possible for both of these atoms to get full outer shells by sharing as happens in this type of bonding. A few more examples are used to consolidate this understanding before quick competition is used to check the understanding so far. Moving forwards, a step by step guide shows students how to draw dot and cross diagrams using the same techniques as was utilised with the hulas.
This lesson has been written for GCSE students but could be used with higher ability KS3 students.
