The Atom Poster

• Draw what you think the atom looks like

• Drawing must include the atom and a color coded key.

The Atom – Day 1 The Atom – Day 2

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)

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?

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)

Together they make gases,And liquids like molasses,And all the solid masses,The Atoms Family




Neutrons can be found,Where protons hang around;Electrons they surroundThe Atoms Family.
