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.

surrounding the atomic symbol.
Oxygen and Chlorine Atoms
Elements within the same group have
the same electron-dot structure.
