Families on the Periodic TableElements 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 1Hydrogen is not a member, itis a non-metal1 electron in the outer shellSoft and silvery metalsVery reactive, esp. with waterConduct electricityImage: http://www.learner.org/interactives/periodic/groups2.html
ALKALINE EARTH METALSGroup 22 electrons in theouter shellWhite andmalleableReactive, but lessthan Alkali metalsConduct electricity
TRANSITION METALSGroups in the middleGood 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 33 electrons in theouter shellMost are metalsBoron is ametalloid
CARBON FAMILYGroup 44 electrons in theouter shellContains metals,metalloids, and anon-metal Carbon(C)
NITROGEN FAMILYGroup 55 electrons in theouter shellCan shareelectrons to formcompoundsContains metals,metalloids, andnon-metals
OXYGEN FAMILYGroup 66 electrons in theouter shellContains metals,metalloids, andnon-metalsReactive
HalogensGroup 77 electrons in theouter shellAll are non-metalsVery reactive areoften bonded withelements fromGroup 1
Noble GasesGroup 8Exist as gasesNon-metals8 electrons in theouter shell = FullHelium (He) hasonly 2 electrons inthe outer shell = FullNot reactive withother elements
Rare Earth MetalsSome areRadioactiveThe rareearths aresilver, silvery-white, or graymetals.Conductelectricity
