Covalent bonding | Developing understanding | 14–16 years

Developing understanding is a series of resources that encourage learners to connect their thinking at the macroscopic, sub-microscopic and symbolic levels. In this covalent bonding worksheet learners think about representing simple covalent and giant covalent structures using a variety of different diagrams and physical models. They use these representations to predict the number of covalent bonds that atoms will make and the shape of the molecules they will form. Icons in the margin indicate which level of understanding each question is developing to help prompt learners in their thinking. As a result, learners should develop more secure mental models to support their understanding of this topic.
