Lewis structures (also known as Lewis 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 Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds.

The Lewis structure was named after Gilbert N.

Lewis, who introduced it in his 1916 article The Atom and the Molecule.

Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

A chemical compound (or just compound if used in the context of chemistry) is an entity consisting of two or more atoms, at least two from different elements, which associate via chemical bonds.

There are four types of compounds, depending on how the constituent atoms are held together: molecules held together by covalent bonds, ionic compounds held together by ionic bonds, intermetallic compounds held together by metallic bonds, and certain complexes held together by coordinate covalent bonds.

Many chemical compounds have a unique numerical identifier assigned by the Chemical Abstracts Service (CAS): its CAS number.

Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule.

It determines several properties of a substance including its reactivity, polarity, phase of matter, color, magnetism and biological activity.

The angles between bonds that an atom forms depend only weakly on the rest of molecule, i.e. they can be understood as approximately local and hence transferable properties.

In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment.

A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

Molecules are distinguished from ions by their lack of electrical charge.

However, in quantum physics, organic chemistry, and biochemistry, the term molecule is often used less strictly, also being applied to polyatomic ions.
