    Hi
    I demo an atom by putting clay globs on the board .... I use two colors, one for the protons and one for the neutrons. First I start with something like Helium . Do the demo. the same way, putting 6 red globs and 6 green globs on the board. When it comes to the electrons, put 2 on the inside of the bowl and then put the other 4 on the outside of the bowl. In this way you can introduce energy level and show that only 2 go on the first level. Don't worry about the next levels because there will always be some student who will wonder how many electrons fit in the second level. Then you have your nice segway into energy levels and the amount of electrons they hold. In the end, we draw atoms and I assign them one to draw for homework. My fifth graders really like this.
