Model Atom

Aim: To make a model of a atom. 

Method: 

1. Choose an Atom to make (one between Hydrogen and Neon) 

2. Work out how many protons, neutrons and electrons it has.

3. Assign Protons and neutrons to a particular color bead.  

4. Get a ball of blue tac and stick the protons and neutrons to this to make your nucleus. 

5. Cut out the appropriate electron shells and draw on the electrons with vivid.

6. Connect the nucleus and electron shells with a piece of string. 

7. Create a label to go above the model so people know what you have created.  

Results:

Discussion: 

- Atomic number - 3 / Number of Protons and Electrons is the atomic number / Mass number - 7 / Number of Neutrons is the mass number. 

- Protons - 3 / Electrons - 3 / Neutrons - 4

- First shell can only have 2, Second shell can have 8 and third shell can also only have 8.

- Although Lithium is a metal it is soft enough to cut with a knife. 

- Along with Hydrogen and Helium, lithium was one of the three elements produced in large amounts of the Big Bang.

Conclusion: 

It worked really well and it lasted a while after it was created. If I were to make this again I would change the element to something a bit lighter so it would hold together.
