Chemistry - Chemical Bonding - Lewis dot structures - Lewis Structure Workshop

A step-by-step Lewis structure builder. The child follows a method for 6 molecules: H₂, H₂O, NH₃, CH₄, CO₂, HCN. For each, the guided steps are: Step 1: Count total valence electrons (e.g., H₂O: 1+1+6 = 8). Display counter. Step 2: Identify central atom (usually least electronegative, NOT hydrogen).
