This resource contains a 40+ page PowerPoint with animations on each stage of a Time of Flight (TOF) Mass Spectrometer, including vapourisation, ionisation, ion drift, electric field and ion detection. It explains how to interpret a Mass Spectrum of isotopes and moleules. Including: How to predict the mass spectrum of diatomic molecules with 1:1, 1:2 and 1:3 ratios, with explanations examples and questions. There are questions to check understanding and a sheet of calculations for students to try with explanations of how the answers are calculated. It contains 4 exam style questions based on AQA A Level questions with answers on the PowerPoint. Slides have a Learning Objectives linked to the AQA Syllabus so that everything is covered.

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 resource which uses the new up to date Hazard Symbols. Each sheet has the name of each hazard symbol, the symbol itself, a description of the Hazard, an example of which chemical has that hazard and an image to help them remember. This will help with Lab safety. This is part of a full lesson where students are taught how to use hazard symbols and hazcards to plan a safe practical: https://www.tes.com/teaching-resource/planning-safe-practicals-using-hazcards-12407118 Please feel free to visit my shop which contains more free (and paid) resources: https://www.tes.com/teaching-resources/shop/stephenkemp193 Thank you.

This resource contains a 30+ page Power Point (and pdf ) to guide students through the new Hazard symbols, their names, hazards and controls (precautions) that are needed in each case. Students have three tasks, a sorting activity, a memory activity and a longer activity which aims for them to think about the hazards, risks and more importantly the controls that need to be put into place to perform the practical safely. The activity contains: Four “fake” chemical Hazcard sheets Four Scenarios to challenge their thinking Posters of the new Hazard symbols with information on each Miniplenary to test knowledge gained. The free poster of the new hazard symbols can be found here: https://www.tes.com/teaching-resource/new-hazard-symbols-meanings-with-examples-for-lab-safety-12266717 Please check out my shop for more free (and paid) resources: https://www.tes.com/teaching-resources/shop/stephenkemp193 Thank you

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.
