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.
