This resource explains how to write the electronic configuration of the first 36 elements in terms of their shells, sub shell and orbitals. It covers the AQA syllabus, but can be used with others. It contains a 30+ page Power Point which explains how electrons fill up the lowest energy levels first, how electrons prefer to stay unpaired and the rather tricky transition metal 4s/3d energy levels. It explains how to write the configuration for neutral atoms as well as ions and contains a page of questions, based around exam questions from AQA. Questions have comments from the examiners report to say how difficult students in the exam found this type of question. It also contains: Periodic Table with all configurations Student sheet with diagrams on for students to add notes to (or cut out and stick in diagrams) Help sheet to practice configuration Question sheet with answers provided on the Power Point Homework/Extra Questions sheet to challenge the most able An animated slide that shows all 36 configurations on an energy level diagram and position on the Periodic table.

This is a helpsheet that uses the circle/ring the formula method to stop students from the misconception of changing the subscripted formula. Students can use this to help them answer questions until they don’t need this scaffolding. There are a lot of balancing equation question sheets, but not many free methods. Hope this is useful.

This resource is a booklet with lists of misconceptions, strategies for overcoming them, and quizzes for ascertaining main misconceptions in Forces, Electricity etc. Update: Want to test how many Christmas misconceptions your students have? Try this new free quiz here: https://www.tes.com/teaching-resource/christmas-quiz-free-misconceptions-12448241 It is research based, but written in a practical way and focuses on the use of models, analogies, CASE, interviewing and other strategies. The most useful part I believe is the lists of misconceptions and a comprehensive index of keywords to help you find the common misconception for that topic/keyword. Thank you for making it is one of my most downloaded resources.
