🔗 Shared Electron Pairs: Single Bond, Double Bond, and H₂O

Three molecular models: H₂ molecule (two small red hydrogen spheres sharing one electron pair), O₂ molecule (two large blue oxygen spheres sharing two electron pairs — double bond), and H₂O molecule (one blue oxygen sphere bonded to two red hydrogen spheres in a V-shape at 104°). GCSE Chemistry revision — covalent bonding.
