  1. Valence Electrons: ELECTRONS AVAILABLE FOR BONDING

  2. CA Standards • Students know how to use the periodic table to determine the number of electrons available for bonding. • Students know how to draw Lewis dot structures.

  3. Definition Valence electrons are electrons in the outmost shell (energy level). They are the electrons available for bonding.

  4. Group 1 (alkali metals) have 1 valence electron

  5. Group 2 (alkaline earth metals) have 2 valence electrons

  6. Group 13 elements have 3 valence electrons

  7. Group 14 elements have 4 valence electrons

  8. Group 15 elements have 5 valence electrons

  9. Group 16 elements have 6 valence electrons

  10. Group 17 (halogens) have 7 valence electrons

  11. Group 18 (Noble gases) have 8 valence electrons, except helium, which has only 2

  12. Transition metals (“d” block) have 1 or 2 valence electrons

  13. Lanthanides and actinides (“f” block) have 1 or 2 valence electrons

  14. Dot Notations An atom’s valence electrons can be represented by Lewis dot notations.

  15. Dot Notations – Period 2 Lewis dot notations for the valence electrons of the elements of Period 2.
