If looking at Lithium on the Periodic Table of Elements you will see that it has 6.94 Atomic weight and the atomic number is 3. It is a fairly small and simple atom since it has only three protons, four neutrons and three electrons.
Victoria painted Styrofoam balls to reflect a Lithium atom. She painted the protons blue; neutrons yellow and the electrons red.
In the picture above she is gluing the balls together to make the Lithium Atom model. This model will be submitted into the County 4-H Fair as part of her project. for the submission into the fair, we will be adding the electrons onto wire that will represent the elliptical lines. I will post pictures prior to submission of the fair in another post.
