ELECTRONS AVAILABLE FOR BONDINGValence Electrons: ELECTRONS AVAILABLE FOR BONDING
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.
Definition Valence electrons are electrons in the outmost shell (energy level). They are the electrons available for bonding.
Group 1 (alkali metals) have 1 valence electron
Group 2 (alkaline earth metals) have 2 valence electrons
Group 13 elements have 3 valence electrons
Group 14 elements have 4 valence electrons
Group 15 elements have 5 valence electrons
Group 16 elements have 6 valence electrons
Group 17 (halogens) have 7 valence electrons
Group 18 (Noble gases) have 8 valence electrons, except helium, which has only 2
Transition metals (“d” block) have 1 or 2 valence electrons
Lanthanides and actinides(“f” block) have 1 or 2 valence electrons
Dot Notations An atom’s valence electrons can be represented by Lewis dot notations. 1 valence e- X 2 valence e- 3 valence e- 4 valence e- 5 valence e- 6 valence e- 7 valence e- 8 valence e-
Li Be B C N O F Ne Dot Notations – Period 2Lewis dot notations for the valence electrons of the elements of Period 2. lithium Li beryllium Be boron B carbon C nitrogen N oxygen O fluorine F neon Ne

Atomic Structure & Periodic Table
PERIODIC TABLE FAMILIES
Filling in the Periodic Table. 1. Label the following: alkali family, alkaline earth family, noble gas family, chalcogen family, halogen family, lanthanide.
Element Family Jeopardy
Dimitri Mendeleev discovered that elements when arranged by mass seemed to organize themselves in other ways as well.
Bell Work Write down the 7 major families on the periodic table and tell which block they are in…..hint look at figure 6.8 page 183.
