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-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.

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

earths are silver, silvery-white, or gray metals.
Conduct electricity
