                                   Periodic Table Notes 
         History               Dimitri Mendeleev (1860s)                                                                  Each energy level can hold a specific # of electrons 
                               Noticed patterns when elements were arranged in                                            Level 1 (closest to nucleus) = 2 e- max 
                                                                                                                                         -

                                                                                                                                         -
                               Noticed blank spaces left on his table and concluded                                       Level 3 = 8 e max 
                                they were spaces for ________________________________                 Valence              Electrons located in the ______________________________ 
         Modern                (early 1900s to present)                                              Electrons            VERY important because they determine an element’s 
         Periodic Table        Arranged in order of increasing                                                             ___________________________

         Groups/               Up & down                                                                                   are involved when elements form _____________________ 
         Families              Columns                                                               Valence              Group #          # VEs                 Reactivity 
                               Elements in a group/family have ______________________                Electrons and           1                          
                               because they have the same number of                                  Periodic Table          2
