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 21 – 22: why do the alkali metals get more reactive as you go down the group? This question can be cold called to the class and the answer is on slide 22 Slide 23: independent practice - A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest.

How can equations be balanced using oxidation states? How can half equations be combined to make an ionic equation? How do you write half equations with hydroxide ions? All this and more covered in this comprehensive lesson with questions and answers! This is a Year 12 A level lesson for Edexcel International Unit 2 – WCH12, 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) Slides 3 – 5: Recap on writing ionic equations. Slide 6 – Rules for constructing half equations Slides 7 – 13: Three worked examples (see video preview) with animations which move you and your students effortlessly through the working out to write two half equations and then combine them to make the ionic equation Slide 14 - 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 15 – 18: This is another worked example, this time involving hydroxide ions, which adds another layer of complexity. All the steps of the working out are animated in a seamless sequence, so that all you need to do is click (and understand the method, of course!) Slides 19 – 20: Introduces balancing equations using oxidation states. There are two worked examples Slide 21 - learning pit-stop to check students’ learning. A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest.

How can oxidation states be used to work out IUPAC systematic names for compounds? What do roman numerals represent in a name? What is an oxoanion? All this and more covered in this comprehensive lesson with questions and answers! This is a Year 12 A level lesson for Edexcel International Unit 2 – WCH12, 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.

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 – Introduction to the variable oxidation states which transition metals and non-metals like nitrogen can have Slide 4 – What are systematic names and how should roman numerals be used? Slides 5 – 7: Worked examples. Students are encouraged to attempt example 2 and 3 on a MWB (mini whiteboard) first Slides 8 – 10: Students are presented with a table showing the formulae of different oxoanions and their non-systematic names, e.g. phosphite. Perchlorate, hypochlorite, etc. This will be important for the next activity. Print the table for them by printing slides 9 – 10 Slide 11 – Independent practice – students are given formulae and non-systematic names and must give the IUPAC name. Answers animate on the screen as you click Slides 12 – 14: Students will be taught how to deduce the formula of a compound from the systematic name. There is a detailed, worked example and an independent practice task with answers Slides 15 – 18: Exam questions with mark scheme answers (included with the purchase of this resource) If you have a positive experience with the resource, please leave a positive review!
