Molecules have shapes

Molecular geometry describes the three-dimensional arrangement of atoms. Electron-pair repulsions provide a remarkably useful first model for many main-group molecules.

Shape matters because it influences polarity, intermolecular interactions and ultimately many physical and chemical properties.

Chemical bonding describes how atoms are held together through interactions involving electrons and nuclei. Ionic, covalent and metallic models highlight different limiting behaviours rather than three completely isolated worlds.
