From atoms to molecules

Electronegativity is a model for an atom’s tendency to attract electron density when it is bonded.

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.

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