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.
