Model atom - Science

 Model Atom

Aim - To make a model 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 colour 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 - Here is a picture of my model atom that I made.

Discussion -

An atomic and mass number is the numbers by the symbol. So the atomic number is the number that represents their place in the periodic table. Which is normally the number placed in the top left corner of the box . The mass number at the bottom of the box underneath the element which is made up by the protons, neutrons and electrons. 

The element I chose was carbon it had 8 protons and 6 neutrons/electrons, and the mass number was 12.

Electron arrangement - On the first shell the maximum of electrons allowed are 2 electrons on the next shell the maximum is 8 shells and the third shell the maximum is 8 and so on. My element their was 2 on the first shell and 4 on the next shell because their were only 6 electrons.

2 interesting facts -  Carbon gets its name from the Latin word carbo, which means coal in Latin.
