Lewis structure
diagrams for the bonding between atoms of a molecule and lone pairs of electrons / From Wikipedia, the free encyclopedia
The Lewis structures, also called Lewis-dot diagrams or electron dot diagrams or Lewis dot structure are pictures that show the bonding between a pair of electrons and the atoms of a molecule.
Each dot represents one electron. Two dots side by side represent a lone pair of electrons.
To show a bond between atoms, a line representing a pair of shared electrons is placed between the two atoms. This is showing water also known as H2O.
