									    The Atoms Family was created by Kathleen Crawford, 1994
Presentation developed by Tracy Trimpe, 2006, http://sciencespot.net/
    How big is an Atom?
• The average size atom (Al) is about
  0.00000003 cm.
• It would take a stack of 50,000
  aluminum atoms to equal the
  thickness of a sheet of aluminum foil.
• That’s Small!!!!
The Language of Chemistry
• CHEMICAL ELEMENTS                -
 – pure substances that cannot be decomposed by ordinary
   means to other substances.




                       Aluminum

                                                 Bromine
     Sodium
 The Language of Chemistry
• The elements, their
  names, and symbols
  are given on the
 PERIODIC
 TABLE
• How many elements
  are there?
The Periodic Table




  Dmitri Mendeleev (1834 -
   1907)
   What’s Inside an Atom?
• An atom is made up of a team of
  three players: protons, neutrons, and
  electrons
• They each have a charge, mass, and
  a location
           The Atom
An atom consists of a
• nucleus
   – (of protons and neutrons)
• electrons in space about the nucleus.

The Atoms Family Story
In the center of Matterville, there is a
place called the Nucleus Arcade,           Name:
where two members of the Atoms             Patty Proton
Family like to hang out. Perky             Description:
Patty Proton, like her sisters, is         Positive
quite large with a huge smile and          Favorite Activity:
eyes that sparkle (+). Patty is always     Hanging out at the Nucleus Arcade
happy and has a very positive
personality. Nerdy Nelda Neutron
                                           Name:
is large like Patty, but she has a
                                           Nelda Neutron
boring, flat mouth and eyes with zero
expression (o). Her family is very         Description:
apathetic     and     neutral     about    Neutral
everything. Patty, Nelda, and their        Favorite Activity:
sisters spend all their time at the        Hanging out at the Nucleus Arcade
arcade.
Around the Nucleus Arcade, you will
find a series of roadways that are used     Name:
by another member of the Atoms Family,      Elliott Electron
Enraged Elliott Electron. Elliott races     Description:
madly around the Arcade on his bright       Negative
red chrome-plated Harley-Davidson. He
                                            Favorite Activity:
rides so fast that no one can be sure
                                            Racing around the arcade
where he is at any time. Elliott is much
smaller than Patty and Nelda and he is
always angry because these bigger
relatives will not let him in the Arcade.
He has a frown on his face, eyes that are
squinted with anger, and a very negative
(-) attitude.
The first energy street can only hold
only two Electron brothers. The second
energy street, called the Energy
Freeway, can hold 8 brothers. The third
energy street, called the Energy
Superhighway, can hold 18 of the
brothers.                                  Energy Superhighway
                                           Can hold 18 electrons

  Energy Freeway
    Can hold 8
     electrons


                                          Nucleus Arcade
   Energy Street                          Contains protons & neutrons
    Can hold 2
     electrons
The morale of Matterville is stable as long as each negative Electron brother
is balanced out by one positive Proton sister. The number of residents in
Matterville depends on the Proton and Neutron families.

Challenge: What would happen to the morale of Matterville if one Elliott
Electron was kidnapped?
Challenge 2: What would happen to the morale of Matterville if one Elliott
Electron moved to Matterville?

1st Verse:                        3rd Verse:
They’re tiny and they’re teeny,   Neutrons can be found,
Much smaller than a beany,        Where protons hang around;
They never can be seeny,          Electrons they surround
The Atoms Family.                 The Atoms Family.

2nd Verse:                        Chorus:
Together they make gases,         They are so small.
And liquids like molasses,        (Snap, snap)
And all the solid masses,         They’re round like a ball.

                                  They’re everywhere.
                                  Can’t see them at all.
