Families on the Periodic TableElements on the periodic table can be grouped into families bases on their chemical properties.Each family has a specific name to differentiate it from the other families in the periodic table.Elements in each family react differently with other elements.
ALKALI METALS
Group 1Hydrogen is not a member, it is a non‐metal1 electron in the outer shellSoft and silvery metalsVery reactive, esp. with waterConduct electricity

ALKALINE EARTH METALSGroup 22 electrons in the outer shellWhite and malleableReactive, but less than Alkali metalsConduct electricity
TRANSITION METALSGroups in the middle
Good conductors of heat and electricity.Some are used for jewelry.The transition metals are able to put up to 32 electrons in their second to last shell.Can bond with many elements in a variety of shapes.
CARBON FAMILY Group 44 electrons in the outer shellContains metals, metalloids, and a non‐metal Carbon (C)
NITROGEN FAMILY Group 55 electrons in the outer shellCan share electrons to form compoundsContains metals, metalloids, and non‐metals
OXYGEN FAMILY Group 66 electrons in the outer shellContains metals, metalloids, and non‐metalsReactive
HalogensGroup 77 electrons in the outer shellAll are non‐metalsVery reactive are often bonded with elements from Group 1
Noble GasesGroup 8Exist as gasesNon‐metals8 electrons in the outer shell = FullHelium (He) has only 2 electrons in the outer shell = FullNot reactive with other elements
