Atomic orbitals and electronic configurations lesson, plus: 1s notation, electrons-in-boxes, Aufbau principle, Hund’s rule, and chromium and copper exceptions! This is a Year 12 A level lesson for Edexcel International Unit 1 – WCH11, but it can also be used for all UK exam boards. All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides (which are best opened on Microsoft PowerPoint) is as follows: Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time. Slide 2 - Lesson objectives (see thumbnail image) Slide 3 – Electrons do not orbit the nucleus!! Drill this into their heads! Slide 4 – 5: Electrons in classical physics and quantum physics. There is an embedded video by Dr Quantum which explores Young’s double slit experiment Slides 6 – 7: The Heisenberg uncertainty principle is discussed Slide 8 – explaining electrons using quantum theory Slide 9 – energy level diagram for sodium Slide 10 –14 : sub-division of quantum shells into sub-shells and orbitals fully explained Slides 15 – 16: shapes of orbitals discussed Slide 17 – learning pit-stop to check students’ learning. A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest. Answers animate onto the screen when you click Slides 18 – 23: Electronic configurations introduced here with the Aufbau principle and Hund’s rule Slide 24 – Worked examples of electrons-in-boxes and 1s notation Slide 25 - learning pit-stop to check students’ learning. A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest.
