  1. Chapter 7-1Electrons and their Energy LevelsPart 2

  2. Energy Levels • The period on the periodic table represents the number of energy levels of electrons in an atom. • example: Carbon is in period 2 because it has 2 energy levels

  3. Valence Electrons • Valenceelectrons are located only in the outer energy level. • Outer energy levels are considered full or stable (inert) with eight electrons. • Example: Neon has eight valence electrons. The noble gases are stable or inert. --Bohr Sketch --Lewis Structure

  4. There is a maximum number of electrons for each energy level. • Energy levels do not have to be filled to the maximum before a higher energy level begins. • Example: Nickel electron configuration Ni 2 8 16 2

  5. Valence electrons determine how an atom will react with other atoms.

  6. Lewis Structures or Electron Dot Formulas show only valence electrons. • Eight electrons (stable) is the most you can show on any atom. • The noble gases have a full outer energy level and are stable or inert.
