    Periodic table-families Periodic table-families Presentation Transcript

    • Families on the Periodic TableElements on the periodic table can be grouped intofamilies bases on their chemical properties.Each family has a specific name to differentiate itfrom the other families in the periodic table.Elements in each familyreact differently withother elements.
    • ALKALI METALSGroup 1Hydrogen is not a member, itis a non-metal1 electron in the outer shellSoft and silvery metalsVery reactive, esp. with waterConduct electricityImage: http://www.learner.org/interactives/periodic/groups2.html
    • ALKALINE EARTH METALSGroup 22 electrons in theouter shellWhite andmalleableReactive, but lessthan Alkali metalsConduct electricity
    • TRANSITION METALSGroups in the middleGood conductors ofheat and electricity.Some are used forjewelry.The transition metalsare able to put up to 32electrons in theirsecond to last shell.Can bond with manyelements in a variety ofshapes.
    • BORON FAMILYGroup 33 electrons in theouter shellMost are metalsBoron is ametalloid
    • CARBON FAMILYGroup 44 electrons in theouter shellContains metals,metalloids, and anon-metal Carbon(C)
    • NITROGEN FAMILYGroup 55 electrons in theouter shellCan shareelectrons to formcompoundsContains metals,metalloids, andnon-metals
    • OXYGEN FAMILYGroup 66 electrons in theouter shellContains metals,metalloids, andnon-metalsReactive
    • HalogensGroup 77 electrons in theouter shellAll are non-metalsVery reactive areoften bonded withelements fromGroup 1
    • Noble GasesGroup 8Exist as gasesNon-metals8 electrons in theouter shell = FullHelium (He) hasonly 2 electrons inthe outer shell = FullNot reactive withother elements
    • Rare Earth MetalsSome areRadioactiveThe rareearths aresilver, silvery-white, or graymetals.Conductelectricity
