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 METALSGroup 1Hydrogen is not a member,
it is a non-metalAll are metals and solid at
room temp1 Valence ElectronSoft and silvery, shinyVery reactive, esp. with
waterConduct electricity

ALKALINE EARTH METALSGroup 2MetalsSolids at room
temp2 electrons in the
outer shellWhite, silvery,
and malleableReactive, but less
than Alkali metalsConduct
electricity
TRANSITION METALSMetalsAlmost all are
solids at room temp (Hg)
Good conductors of heat and electricity.
1 or 2 Valence Electrons
Less Reactive than Alkali and Alkaline Earth
Can bond with many elements in a variety of shapes.
BORON FAMILY Group 33 electrons in
the outer shellMost are metalsBoron is a
metalloidReactiveSolid at room
temp
CARBON FAMILY Group 44 electrons in the
outer shellContains 3
metals, 2 metalloids, and 1 non-metal Carbon (C)
Reactivity variesSolids at room
temp
NITROGEN FAMILY Group 55 electrons in the
outer shellCan share
electrons to form compounds
Contains 2 metals, 2 metalloids, and 2 non-metals
Reactivity VariesNitrogen is the
only gas at room temp, rest are solids
OXYGEN FAMILY Group 66 electrons in
the outer shellContains 2
metals, 1 metalloid, and 3 non-metals
ReactiveOxygen is a gas,
the rest are solids at room temp
HalogensGroup 77 electrons in the
outer shellNon-metals,
Uus is unknownVery reactive -
are often bonded with Group 1 Alkali Metals
Has 2 gases, 1 liquid (Br), and 2 solids
Noble GasesGroup 8Exist as gasesNon-metals8 electrons in the
outer shell = FullHelium (He) has
only 2 electrons in the outer shell = Full
Not reactive with other elements
Rare Earth MetalsSome are
RadioactiveThe rare
earths are silver, silvery-white, or gray metals.
Conduct electricity
