Encourage learners to think about how atoms and ions are represented and what this means at the sub-microscopic level

Developing understanding is a series of resources that encourage learners to connect their thinking at the macroscopic, sub-microscopic and symbolic levels. In this atoms and ions worksheet learners are encouraged to distinguish between atoms and ions and think about what these differences mean at the sub-microscopic level. 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.
