The Atom Poster
• Draw what you think the atom looks like
• Drawing must include the atom and a color coded key.

On BackName, Date, Period
SPS1a. Examine the structure of the atom in terms of proton,
neutron, and electron.
Activator:
Draw what you think an atom looks like, including the protons, neutrons, and
electrons (label).
Copy this into your notes:
Now label the three different parts using these words:
1.Electron (s)2.Proton(s)3.Neutron(s)
Now label the words as being the following:
1. Positive (+)2. Negative (-)3. Neutral (NA)
The Atom
Was first named bydefinition

Makes up
The smallest piece of matter that still has the chemical and physical
properties of that matter.
Democritus in 400 B.C.
All the matter in the universe
• Protons particles with
positive charges found in nucleus
of atom
• Determines the type of atom
• Neutrons - particles with no charge found in the nucleus
of the atom
• # of neutrons can vary
• Electrons – particles with
negative charge
• Found around the outside of the
atom
• Determine how atom will react
with other atoms
The Atom Poster
• Draw what you think the atom looks like
• Drawing must include the atom and a color coded key.
• Include the correct number of protons, electrons, and neutrons.

Draw Today
TOD:
• What was your drawing from yesterday missing?
Atoms
Look at the back of your notes from yesterday.
• Are all the pictures of atoms?
• How are they similar?
• How are they different?
Bohr Model
What is a Bohr Model?
• Shows all the protons, neutrons, and electrons contained within an atom.
• Protons and neutrons are drawn in the Nucleus.
• Electrons are drawn on ENERGY LEVELS or SHELLS or ELECTRON CLOUDS (the rings found around the nucleus).
Energy Levels
• Energy levels can only hold a certain amount of electrons.
Energy Level Maximum Number of Electrons
1 2 electrons
2 8 electrons
3 18 electrons
4 32 electrons
5 50 electrons

How do the Structures of Atoms Differ?
Atomic number
Mass number
Atomic mass
Atomic Number = the number of protons
Identify the type of atom, the number of protons and the number of electrons:
Atomic number
16
43
4
6
Mass Number – the number of protons and neutrons
• Fluorine 9 protons + 10 neutrons = 19 • Carbon 6 protons + 6 neutrons = 12
Atomic Mass (Weight) = the avg of the # of protons plus the # of neutrons for all the diff kinds of one type of atom
Proton 1.0053 amu
Neutron 1.0087 amu
Electron 0.000549 amu (ignore)
Name: Nelda Neutron
Description:Neutral
Favorite Activity:Hanging out at the Nucleus Arcade
In the center of Matterville, there is a place called the Nucleus Arcade, where two members of the Atoms Family like to hang out. Perky Patty Proton, like her sisters, is quite large with a huge smile and eyes that sparkle (+). Patty is always happy and has a very positive personality. Nerdy Nelda Neutron is large like Patty, but she has a boring, flat mouth and eyes with zero expression (o). Her family is very apathetic and neutral about everything. Patty, Nelda, and their sisters spend all their time at the arcade.
The Atoms Family Story
Name: Patty Proton
Description:Positive
Favorite Activity:Hanging out at the Nucleus Arcade
Name: Elliott Electron
Description:Negative
Favorite Activity:Racing around the arcade
Around the Nucleus Arcade, you will find a series of roadways that are used by another member of the Atoms Family, Enraged Elliott Electron. Elliott races madly around the Arcade on his bright red chrome-plated Harley-Davidson. He rides so fast that no one can be sure 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.
Nucleus ArcadeContains protons & neutrons
Energy Freeway Can hold 8 electrons
Energy Superhighway Can hold 18 electrons
Energy Street 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:They’re tiny and they’re teeny,Much smaller than a beany,They never can be seeny,The Atoms Family.Chorus
2nd Verse:Together they make gases,And liquids like molasses,And all the solid masses,The Atoms FamilyChorus
3rd Verse:Neutrons can be found,Where protons hang around;Electrons they surroundThe Atoms Family.Chorus
Chorus:They are so small.(Snap, snap)They’re round like a ball.(Snap, snap)They make up the air.They’re everywhere.Can’t see them at all.(Snap, snap)
