This website allows the user to build their own Carbon Atom out of elementary particles (up quarks, down quarks, and electrons). As protons, neutrons, and electrons are added to the atom, the atom changes from one element to another. From hydrogen the atom changes into helium, then lithium, and on up through the Periodic table until it finally becomes carbon. If, while being built, the balance between protons, neutrons, and electrons is not sufficiently maintained, the atom will either become radioactive and decay, or become so ionized that it will attach itself to a molecule outside the building area. In either case, the user must start over. The activity is over when the atom changes into carbon. Read the guides for assistance.
