It is allows you to visualize the bonds between atoms in three dimensions. the elements are
represented by colored balls and the bonds by flexible rods. Each atom has the same number of holes
as the number of Valence electrons in needs to complete its outer shell. for example, carbon has
four electron in its outer shell, so it needs four more to be complete. the black carbon ball has
four holes, allowing it to form four bonds and gain the electrons it needs . with this set you can
demonstrate single bonds using the short white rods, and double or triple bonds using the long gray
rods.
