Digital file- Question & Answer sheet - AQA GCSE Combined Science - Ionic Bonding

By using this, students should be able to describe the limitations of using dot-and-cross diagrams, ball-and-stick models, and two- and three-dimensional diagrams to represent giant ionic structures. Students should be able to explain that these models simplify the structure and may not accurately show the size, scale, arrangement, or number of ions present in the giant lattice. Students should also be able to describe how electrons are transferred when metals react with non-metals, explain how this forms positively and negatively charged ions with a noble gas electronic structure, and use the group number of an element to predict the charge of the ion formed.
