This task is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the 'Bonding & Structure’ SoW.
 
This activity contains a set of differentiated questions worth 20 marks in total, it also includes additional extra challenge tasks for higher ability students to complete. This worksheet could be used as a homework or as an extension or revision activity in class.
 
I have included a comprehensive mark scheme for teacher or self-assessment of the work, there are also details of grade boundaries which I use to RAG pupils work against their target grades, a full explanation of how I do this is included.
