The bonding diagram builder draws dot and cross diagrams for ionic and covalent compounds in steps. Start from the separate atoms, show the transfer or the sharing, and finish on the full answer, the way you would build it on the board.
A hand-built replica of the real builder page, not a screenshot. Every control shown exists in the product.
Dot and cross diagrams are marked on the detail, the brackets, the charges, the shared pairs in the overlap. A quick sketch rarely lands all of it, and here each step is drawn the way examiners expect, so what the class copies down is correct.
Step forwards and backwards with the class predicting the next stage before it appears. Twenty seven compounds cover the standard GCSE examples and the harder ones, and any step exports for a worksheet, mid transfer or finished.
Diagnostic multiple choice. Each answer reveals what the class does and doesn't understand.
Click a number and watch it land on a question at random. Built for cold-call questioning.
Automate show, cover, and recall tasks. Great for memorising diagram features or keywords.
Questions beside a visual stimulus. A YouTube clip, diagram, graph, or a paragraph to read closely.
Shell diagrams for atoms and ions, with dots or crosses, hidden electrons and side-by-side comparison.
Curated, balanced GCSE reaction equations, ready to blank for recall.
Generate chemistry calculations with scaffolded, worked solutions.
Every tool turns a few inputs into a clean, exam-ready diagram.
Practical results tables with repeat readings, a mean and an optional anomaly, plus curated reference data.
Upload any diagram and the labels are suggested for you to drag, edit and blank.
