                                                                    Alien   Periodic   Table  
           Learning   Target :   
           I   can   predict   the   relative   chemical   properties   of   elements   based   on   patterns   of   valence   electrons   and   the   periodic  
           trends   of   electronegativity,   ionization   energy,   electron   affinity,   and   atomic   radius.   
            
           Mission :   
           To   correctly   arrange   alien   elements   on   a   blank   periodic   table   using   trends   in   their   physical   and   chemical  
           properties.  
            
           Background   Information :   
           Earth’s   scientists   have   announced   that   they   have   made   contact   with   intelligent   life   on   a   distant   planet.    This  
           alien   planet’s   language   has   been   translated   and   scientific   information   has   begun   to   be   exchanged.    The   planet   is  
           composed   of   the   same   elements   as   Earth.    However,   the   inhabitants   of   the   planet   have   different   names   and  
           symbols   for   them.    Since   the   alien   scientists   do   not   know   the   names   of   our   elements,   they   have   radioed   the  
           following   data   on   the   known   properties   of   the   elements.    Strangely,   but   luckily   there   are   no   transition   or   rare  
           earth   elements   on   the   alien   planet.    This   means   that   their   periodic   table   consists   only   of   the   main   group  
           elements.    
            
           Procedure :  
                1) Listed   below   is   the   data   of   the   properties   for   each   element.   
                2) Be   sure   to   record   your   conclusions   in   the   blank   periodic   table   to   the   right.  
                          a) Place   the   30   elements   in   their   proper   position   on   the   blank   periodic   table.  
                3) Complete   the   analysis   questions   on   the   back   page.  
           Data :  
                1) The   halogens   are   Madrid   (Ma),   Hoffenheim   (Hn),   and   Atalanta   (An).   Liverpool   and   Manchester   are   in  
                     the   same   period   as   Hoffenheim.  
                      
                2) The   chemical   makeup   of   the   alien   planet’s   oceans   seems   to   be   the   same   as   Earth’s   oceans   (saltwater).  
                     When   seawater   is   distilled,   the    liquid    that   is   boiled   off   and   condensed   has   been   shown   to   have  
                     molecules   consisting   of   one   atom   of   Napoli   (Np)   and   two   atoms   of   Dynamo   (Dn)   .   The   solid           left   behind  
                     after   distillation   mainly   consists   of   a   crystal   made   up   of   the   elements   Eindhoven   and   Madrid.  
                      
                3) The   noble   gases   are   Liverpool   (Lv),   Valencia   (Va),   Ajax   (Aj),   and   Roma   (Ro).   Valencia’s   outermost  
                     electrons   fall   into   the   second   energy   level.   The   noble   gas   with   the   greatest   atomic   mass   is   Liverpool.   The  
                     only   noble   gas   without   8   valence   electrons   is   Ajax.  
            
                4) Benfica   (Bn),   Eindhoven   (Ei),   Sporting   (Sp),   and   Manchester   (Mr)   are   all   Alkali   metals.   Of   these,  
                     Liverpool   and   Manchester   are   in   the   same   period,   and   Sporting   has   the   lowest   atomic   mass.  
            
                5) The   lightest   element   on   the   periodic   table   is   called   Dynamo   (Dn).The   most   chemically   active   nonmetal  
                     is   called   Atalanta.   The   most   metallic   element   is   Benfica.   .   The   heaviest   element   on   the   planet   is   Lyon  
                     (Ly).   Remember   that   metallic   character   increases   as   you   go   from   right   to   left   across   the   table   and   as   you  
                     go   down   a   group.   Reactivity   for   metals         typically   increases   as   you   go   from   top   to   bottom   within   a  
                     column   and   for    nonmetals    from   bottom   to   top   within   a   column.  
                      
            
     
     6) The   metalloids   are   Lazio   (Lz),   Besiktas   (Bs),   Arsenal   (Ae),   Schalke   (Sh).   Besiktas   and   Lazio   are   in  
       Group   14.   Besiktas   has   more   protons   than   Lazio.   Villarreal   (Vi)   is   just   a   light   metal   even   though   it’s  
       found   with   the   metalloids.   The   metalloid   with   the   highest   atomic   mass   is   Arsenal,   and   Schalke   is   the  
       metalloid   with   lowest   atomic   mass.  
     
     7) The   element   Chelsea   (Ch)   has   3   valence   electrons.   The   elements   Monaco   (Mc)   and   Salzburg   (Sa)   both  
       have   two   valence   electrons.   Mc   has   5   energy   levels   (rings),   while   Salzburg   had   three.  
        
     8) Porto   (Pr),   Milan   (Mi),   and   Napoli   (Np)   all   have   6   valence   electrons.   Mi   has   a   lower   atomic   number  
       than   Porto.  
     
     9) Both   Barcelona   (Bc)   and   Juventus   (Ju)   have   atoms   with   four   energy   levels.   Stuttgart   (Su)   is   a    black  
       crystal   and   has   4   electrons   in   its   outermost   energy   level.   Juventus   is   less   metallic   than   Barcelona.  
     
     10)Gremio   (Gr),   Sevilla   (Sv),   and   Arsenal   (Ae)   are   all   members   of   Group   15.   Sevilla   has   more   total  
       electrons   than   Gremio.   
        
     11)Flamengo   (Fa)   only   has   4   protons   in   its   nucleus.

                 2) Were   you   able   to   place   some   elements   within   the   periodic   table   with   just   a   single   clue?    Explain   using  
                      examples.  
            
            
            
                 3) Why   did   you   need   two   or   more   clues   to   place   other   elements?   Explain               using   examples .   
            
            
            
                 4) Why   could   you   use   clues   about   atomic   mass   to   place   elements,   even   though   the   table   is   now   based   on  
                      atomic   number?  
            
            
            
                 5) Write   2-3   sentences   describing   which   gr            oup(s)    of   elements   are   not   included   in   the   alien   periodic   table
