This interactive simulation allows students to build and visualise covalent bonds using dot and cross diagrams. Learners explore how atoms share electrons to form stable bonds, with optional valency displays to reinforce electron counting and shell occupancy principles essential to understanding chemical bonding.
Learning objectives: Represent covalent bonds using dot and cross notation | Understand electron sharing and valency in molecular formation | Apply bonding concepts to predict stable molecular structures
