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. Lewis Dot Structures
