Lewis structure

diagrams for the bonding between atoms of a molecule and lone pairs of electrons

Lewis structures (also known as Lewis dot diagrams, electron dot diagrams, Lewis dot formulas, Lewis dot structures, and electron dot structures) are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.


  • A simple way of indicating the covalent bonds in molecules is to use what are called Lewis structures, or electron-dot structures, in which the valence shell electrons of an atom are represented as dots. … Simpler still is the use of Kekulé structures, or line-bond structures, in which a two-electron covalent bond is indicated as a line drawn between atoms.
