Chemistry 1.4 Demonstrate understanding of aspects of selected elements
Key tips
- Be prepared to write and balance chemical equations.
- This topic has subtopics that are unrelated. It may be useful to create separate mind maps or summary pages for each subtopic, such as chlorine, ozone, allotropes of carbon etc.
- Understand the difference between physical properties and chemical reactions
- Create a summary sheet of all the reactions that are needed, for example, acid + base → salt + water.
- Create a table showing the different metals’ reactivity to oxygen, water, or acid, including all observations that you would see.
- Pay attention in practical work! It is often easier to learn things when you have actually seen it happen, rather than just reading about it. However, if you have missed it, you can find many movies on the Internet of different reactions, although it can be time consuming looking for them.
