Atom Mobile Project
Due Date: November 22nd 2019
For this project, you will be creating a mobile of an atom of a specific element. You may create the mobile in any way you choose, but it must hang no longer than 18 inches and should be no wider than 12 inches. Your mobile should be an accurate representation of the element- For example, your atom should include:
Nucleus- should be in the center of the atom and should include the correct number of neutrons and protons
Electron Shell- should have the correct number of levels and should include all the necessary electrons per level
Your mobile should show that there is “empty space” between the nucleus and electrons
The mobile may be created using any type of materials (paper, fabric, 3D objects, clay, etc.). We would like to see a variety of materials used. It must be three-dimensional and may not be mounted on a flat surface. This means that you should not use all drawn pictures or computer generated materials. Be creative! For the hanger you may also use any type of material (sticks, clothes hangers, embroidery hoops, etc.), but the atomic particles must hang freely from it. Do not just tape pictures right onto the hanger. Attached at the top of the mobile, you will need to write the element name, atomic symbol, atomic mass, and atomic number. Hanging from the bottom of the mobile, you will attach a typed paragraph with information about the element. You also need your name and your teacher’s name.
In addition to your mobile, you will need to type a paragraph which will give the reader important information about your element. While writing this paragraph you should be answering these questions:
Name of the element
- o Is it Latin or Greek?
o Why was it chosen?
Characteristics of element
o Is it a metal or non metal
o Is it normally solid, liquid, or gas?
o Is it stable or reactive?
o Does it have a special group it belongs to- Noble Gas, Alkali, etc.
Number of protons
Number of electrons
Number of neutrons
When it was discovered
Who discovered it
Where was it discovered
Where can it be found
o Is it found on earth, in space, in the atomosphere?
Common uses for the element
Any interesting facts
Please print 2 copies of this paragraph- one to attach to the mobile, and one to turn in to the teacher.
Here are some web sites you can use to help find information on your element:

As always, try your best and have fun! If you have any questions do not hesitate to ask.
Helium is a small element. It has only two protons, neutrons, and electrons. Since it has all equal parts, Helium is considered a stable element. It is naturally found in gas form, is odorless and colorless, and is part of the Noble Gases. Helium was discovered by the French astronomer Pierre Janssen in 1868 during a solar eclipse. It was named Helium after the Greek word, “Helios” which means sun. Helium is rare on Earth because it is such a light gas and will escape into space. On Earth it can be found underground and in the atmosphere. Today Helium is used in balloons and blimps because it is lighter than many of the elements in air. It is also mixed with regular air in deep sea diving SCUBA tanks because it is easier to breathe under extreme pressure. Helium is also used in rocket fuel because it is less flammable than other gases. One thing interesting about helium is that it has never been seen bonding with other elements and cannot bond to itself, so it is always found as a single atom.
