I HEART this image of the Periodic Table. http://i.imgur.com/XFpAX.jpgIt is a great way to look at each elements
because there are pictures that represent real life examples of how they are used!

Families on the Periodic TableElements on the periodic table can be
grouped into families/groups based on their chemical properties (AND valence electrons).
Each family/group has a specific name based on reactivity to different elements.
H has no family members (). Hydrogen is is a non-metal.

BrSLT Period 2

Bromine
Group/FamilyHalogen
NON-Metal
Used for photography, medicines, insecticides
From back of your sheet
ALKALI METALSGroup 11 electron in the outer
shell (valence) Soft and silvery metalsVery reactive, especially
with waterConducts electricity

ALKALINE EARTH METALSGroup 22 electrons in the
outer shell (Valence electrons)
White and malleable
Reactive, but less than Alkali metals
Conducts electricity
TRANSITION METALSGroups in the
middle
Good conductors of heat and electricity.
Some are used for jewelry (malleable)
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.
BORON FAMILY Group 33 electrons in the
outer shell (Valence electrons)
Most are metalsBoron itself though
is a metalloid (which means it has metal like properties)
CARBON FAMILY Group 44 electrons in the
outer shellContains metals,
metalloids, and a non-metal Carbon (C)
*Make sure you check the large Periodic table to see if the element you are looking for is a metal, non-metal, gas or metalloid
NITROGEN FAMILY Group 55 electrons in the outer
shellCan share electrons to
form compoundsContains metals,
metalloids, and non-metals
*Make sure you check the large Periodic table to see if the element you are looking for is a metal, non-metal, gas or metalloid
OXYGEN FAMILY Group 66 electrons in the
outer shellContains metals,
metalloids, and non-metals
Reactive *Make sure you check the
large Periodic table to see if the element you are looking for is a metal, non-metal, gas or metalloid
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 = Full
Not reactive with other elements
Rare Earth MetalsSome are
RadioactiveThe rare
earths are silver, silvery-white, or gray metals.
