I need some suggestions on how he should perpare this project..building the atomic structure besides just drawing it on a piece of paper.

save yourself some money and have some fun in the process...buy gum drops, tictacs and licorice. Different color gum drops can represent the protons (11) and neutrons (12) in the nucleus. The licorice will represent the electon energy levels (3 circles) and the tictacs (11)will be the electrons, 2 on the 1st energy level, 8 on the second and 1 on the outer energy level.
Have fun!!!

Step 1 - Gather Information
Before you can build your model, you will need to know how many protons, neutrons and electrons your atom has. If you do not already know how to use the Periodic Table of Elements to find this information, read this page to learn how: http://education.jlab.org/qa/pen_number.html. Here is a direct link to SODIUM: http://education.jlab.org/itselemental/ele011.html
Step 2 - Gather Materials
Now that you know how many protons, neutrons and electrons you will need for your model, it is time to decide what to use to represent them. Ping-pong balls, rubber balls, ball bearings, golf balls and styrofoam balls etc. Basically, anything that is roundish and that can be glued to each other should work. It is helpful if the balls are color coded so that it is easier to tell which balls are protons, which are neutrons and which are electrons. It is also helpful if the electrons are smaller than the protons and neutrons.
Step 3 - Build the Nucleus
The nucleus, the central part of the atom, is made from protons and neutrons. All of your atom's protons and neutrons go in the nucleus.
Step 4 - Place the Electrons
The electrons are found outside the nucleus. How you place them depends on which model of atomic structure is being constructed.
The Planetary Model
The electrons are said to orbit the nucleus much like the planets in the solar system orbit the sun. Depending on the teacher, the actual orbits usually don't matter. Having the right number of electrons is usually good enough.
Step 5 - Things to Remember
It is important to remember that a model is a simplified representation of an object.

Sodium's atomic number is 11. So there will be 3 electron shells.
From inner to outer the number of electrons per shell will be
2
8
1
The atomic mass is approx 23. So we know there will be 11 protons since there are 11 electrons. 23-11 = 12 Neutrons. You could use styrofoam balls and and metal rings or dowels. Just make sure the neutrons and protons are larger than the electrons (though it will definitely not be to scale), and technically not realistic since electrons are not really substantial things but instead waves... but I think this will work for your son :).

That's exactly what P:46 and N:60 mean. You obviously were listening in class. Bravo! Additional Details: Yes, just put the 106 marbles as a core in the middle. Marbles are a bit tricky, but you either superglue them together or bind them all together in the foot of a nylon stocking. Good luck!

Do you mean buidling a model? The best way is to go to the craft store and get one of those large styrofoam balls (nucleus), small styrofoam balls (electrons orbiting around), small felt balls (protons and neutrons), and small wooden dowels (to hold the electrons in orbit.
Just stick the wooden dowels into the large styrofoam ball and sitck the small styrofoam balls to the other end. If your kid has to represent the various valences of the electrons then you should vary the length of the dowels. stick the felt balls onto the large ball to represent the neutrons and protons. Make sense?

Try Google and Wikipedia for detaile info on Sodium.

he can write something about sodium...for example u can include pictures from web and write the main uses. then u can do a presentation and try to find documentaries relating to the discovery of sodium. ask whether the teacher can include a multimedia projector so ur son can present it better...best of luck!!!
