Family Foldable
 You
will need 3 sheets of legal paper.
 Fold the paper in half horizontally so
that you will have six flaps.
 Then fold cut the five bottom flaps in
half exactly.
 In the end you should have 10
separate flaps.

Alkali Metals









Has one valence electron.
Extremely reactive, most reactive of all elements.
The reactivity increases from top of to the bottom.
Softer than group 2 elements.
Lower melting and boiling points.
Reacts violently with water and oxygen.
Oxidizes very fast.
Only found in compounds in nature.
Hydrogen is NOT a member of this group, it is a
non-metal.
Alkaline Earth Metals
Have two valence electrons.
 Metals in group 2A are harder than
metals in group 1A.
 Higher melting and boiling points than
group 1A.
 Only found in compounds in nature.
 Less reactive than group 1A metals but
more reactive than remaining groups.

Transition Metals
Form compounds with distinctive colors
 Will have several oxidation numbers
 Label the columns

Metalloids
Metalloids are elements with properties
that fall between those of metals and
non-metals.
 The metalloids in the remaining groups
will be colored green.
 They include: (list them)

The Boron Family
Have three valence electrons.
 Boron is a metalloid and the remaining
elements are metals.
 Aluminum is strong, lightweight,
malleable, and a good conductor of
electric current.
 Aluminum is the most abundant element
in the earth’s crust.

The Carbon Family





Group 4A contains a nonmetal (Carbon),
two metalloids (silicon and germanium),
and two metals (tin and lead).
Has four valence electrons.
Except for water, most of the compounds in
your body contain carbon.
Silicon is the second most abundant
element in the Earth’s crust.
As you go down the family the elements
become better conductors.
The Nitrogen Family
Group 5A contains two nonmetals
(nitrogen and phosphorous), two
metalloids (arsenic and antimony), and
one metal (bismuth).
 Nitrogen is nonmetal gas, phosphorous
is a solid nonmetal, and bismuth is a
dense metal.
 Properties vary greatly.
 Has 5 valence electrons.

The Oxygen Family (Chalcogens)
Group 6A has three nonmetals (oxygen,
sulfur, and selenium), and two
metalloids (tellurium and polonium).
 Have six valence electrons.
 Oxygen is the most abundant element in
Earth’s crust.

The Halogens
Has 7 valence electrons.
 Fluorine and Chlorine are gases, bromine is
a liquid that evaporates quickly, and iodine is
a solid that sublimes.
 Despite their physical differences, the
halogens have similar chemical properties.
 They are highly reactive nonmetals, with
fluorine being the most reactive and chlorine
a close second.

The Noble Gases
Helium has two valence electrons
 They remaining has eight valence
electrons. [8 electrons in the outer shell
= Full Helium (He) has only 2 electrons
in the outer shell = Full]
 The noble gases are colorless and
odorless and extremely unreactive.
 Exist as gases
 Non-metals
