3. The Atoms Family Story
In the center of Matterville, there is a place called the Nucleus Arcade, where two members of the Atoms Family like to hang out. 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.
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.

4. 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 shiny bike. He rides so fast that no one can be sure where he is at any time.
Elliott is
*much smaller than Patty and Nelda
*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.

5. The first energy street can only hold only two Electron brothers
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.
Matterville
Energy Superhighway Can hold 18 electrons
Energy Freeway Can hold 8 electrons
Nucleus Arcade Contains protons & neutrons
Energy Street Can hold 2 electrons

6. Morale of Matterville
What is Morale?

7. Morale
The general feeling of a group of people (a population). Specifically
how well they feel the group works
how positive or negative they feel about their interactions with others in the group

8. The morale of Matterville is stable as long as each negative Electron is balanced out by one positive Proton.
The population of Matterville depends on the number of Protons and Neutrons.
Challenge: What would happen to the morale of Matterville if one Elliott Electron was kidnapped?

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

Atomic Mass
For oxygen, the atomic number tells us that there are 8 protons in every atom of oxygen we will ever find in the universe.
There are also 8 electrons (because the number of protons and electrons are always equal in a atom.
The atomic mass is about 16 (yes, you will round off the atomic mass). Atomic mass is protons + neutrons. We already know that there are 8 protons, so to get an atomic mass of 16, you would have to have 8 neutrons
8 protons + 8 neutrons = atomic mass of 16

21. Practice Rounding Off To the Nearest 1
*If there is a 5 or a number larger than 5 in the TENTHS place (ie the first number to the right of the decimal), we “round” the number to the next highest number
Example: 15.9 “rounds up” to 16 because there is a “9” in the tenths place.
It makes sense to round this way because is much closer to 16 than to 15
*If there is a number smaller than 5 in the TENTHS place (ie the first number to the right of the decimal), we round the number “down”
Example: 15.3 “rounds down” to 15 because there is a “3” in the tenths place.

22. Round these to the nearest 1!
65.39 rounds off to _______
6.941 rounds off to _______
rounds off to ______
10.81 rounds off to _______
rounds off to ______
