structure of water Lewis structures (also known as Lewis dot diagrams‚ electron dot diagrams‚ and electron dot structures) are diagrams that show the bondingbetween atoms of a molecule and the lone pairs of electrons that may exist in the molecule.[1][2][3] A Lewis structure can be drawn for any covalently bondedmolecule‚ as well as coordination compounds. The Lewis structure was named after Gilbert Newton Lewis‚ who introduced it in his 1916 article The Atom and the Molecule.[4] They are similar
