Assignment: BoilingandMeltingPoints Exploration

AnalysisandConclusions

1. Looking attheline plotsonyourgraph,describehowboiling pointand meltingpointvary with respect to atomicnumber.

1. Nowlook atthesegment ofthegraphbetweenthetwodatapointsmarked withblacksquares. Describe how theboiling pointand meltingpointplotsbehave betweenthesepoints.Beas specificas possible.

1. On yourgraph,thedatapointsbetweentheblack squares are dataforelementswith atomic numbers 3 through9. Locatetheseelementson your periodictable.Whattermordescription wouldyouuse toidentifytheseelementswithrespect totheperiodictable?

1. Nowlook atthegreenlines you createdbyconnectingthethreeboilingpointdatapointsand thethreemeltingpointdatapoints.Foreach oftheselines,describe anytrendsyou see.

1. Locatetheelementsonyourperiodic tablethatyou circledin green on your graph.Whatterm ordescription wouldyouuse toidentifytheseelementswithrespect totheperiodictable?

1. Afterreviewing your answersto questions2 and 4 above, wouldyoudefine boiling pointand meltingpointas a periodictablefamilytrend(verticalgroups),period trend (horizontalrows),or neither?Explainyouranswer.

1. Using theroomtemperatureline (orangeline) and your periodictable,make liststhatidentifythestate ofmatter(gas,liquid,orsolid) in whicheachelementyouplottedexists atroomtemperature.Explainyour answers.
