A symbolic description of the distribution of valence electrons in a molecule. Lewis structures use dots to represent individual electrons and lines to represent covalent bonds.
electron dot structure; dot structure. A model pioneered by Gilbert N. Lewis and Irving Langmuir that represents the electronic structure of a molecule by writing the valence electrons of atoms as dots. Pairs of dots (or lines) wedged between atoms represent bonds; dots drawn elsewhere represent nonbonding electrons.
The representation of the electron arrangement in atoms, ions, or molecules by showing the valence electrons as dots placed around the symbols for the elements
a diagram that illustrates the arrangement of valence electrons (both shared and unshared) within a molecule or polyatomic ion
a representation of covalent bonding in which shared electron pairs are shown as lines or as pairs of dots between two atoms, and lone pairs are shown as pairs of dots on individual atoms
a molecular representation showing atomic connections and valence electrons
A means of showing schematically how valence electrons are distributed among the atoms in a molecule. Also known as the electron-dotsystem, Lewis structure represents pairs of electrons with a symbol rather like a colon, which—depending on the situation—can be placed above, below, or on either side of the chemical symbol. In the Lewis structure, the pairs of electrons involved in chemical bonds are usually represented by a dashed line.

Lewis structures, also called electron-dot structures or electron-dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently-bonded molecule, as well as coordination compounds. The Lewis structure was named after Gilbert N.
