Atoms

 

Today in class we made recreations of Atoms using paper, plastic "nucleus", vivid and string. I made a recreation of a helium atom.

Aim: To make a model of an atom 

The method:

1. Chose an atom to make. (between hydrogen and neon)

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

3. Hydrogen to beryllium use the big beads.

4. Boron to neon just the small beads.

5.  Assign protons and newtons to a particular colour of beads.

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

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

8. Connect the nucleus and electron shell with a piece of string.              Black= neutron Red = proton 

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

Helium is the second element on the periodic table. It has two protons, two neutrons and two electrons making its atomic number 2. The atomic number is how many protons and electrons the atom has. Its mass number 4.0, however, is how many protons and neutrons there are in the atom in total. Since helium has only two electrons its outer shell only has two electrons and because of this helium is very stable. 

Facts about Helium. 

Helium is a colourless, tasteless and odourless gas and its the second most common element in the Universe. and the gas is almost all ways found in its gas state except in very extreme circumstances.
