Limitations of dot and cross diagram gcse

NettetAlternatively, Dot and Cross diagrams may also be used to represent a covalent bond. Covalent dot and cross diagrams operate in the same way as those for ionic molecules. However, in the case of covalent molecules, the diagrams look more like a Venn diagram, with the dot and cross of the covalent bonds contained within the overlap.The … Nettetdescribe the limitations of using dot and cross, ball and stick, two and three dimensional diagrams to represent a giant ionic structure work out the empirical formula of an ionic compound from a given model or diagram that shows the ions in the structure.
