    | • | Why have we been
    so interested in where 
 |  | 
   
    |  | 
   
    |  | the electrons are
    in an atom?  And what is 
 |  | 
   
    |  | 
   
    |  | the importance of
    valence electrons? 
 |  | 
   
    |  | 
   
    | • | Valence e’s are
    involved in_______--the no 
 |  | 
   
    |  | 
   
    |  | of valence e’s
    has an important influence on 
 | 
   
    |  | 
   
    |  | ______ of bonds
    formed. The filled inner 
 |  | 
   
    |  | 
   
    |  | core does not
    directly affect bond 
 |  | 
   
    |  | 
   
    |  | formation.
