Electron Dot Structure or Lewis Dot Structures

Valence Electrons Valence electrons are the electrons in the highest occupied energy level of the atom. Valence electrons are the only electrons generally involved in bond formation. The valence electrons in the s and p orbitals are written around the element symbol. These electrons are then used to determine the number of bonds formed in making a molecule.

Electron Dot Structure or Lewis Dot Diagram (Gilbert Lewis) A notation showing the valence electrons surrounding the atomic symbol.

Oxygen and Chlorine Atoms

Elements within the same group have the same electron-dot structure.
