Our?amazing?chemical molecular model contains 132 atoms, 158 chemical bonds and a set of fullerene sets (60 carbon atoms and 90 bonds), with a total of 444 parts. Almost two times as much as the same product on the market. ? There are three kinds of chemical models that we can achieve: ? ? ? 1.Ball-and-stick models ? ? ? ? ?Ball-and-stick models?use spheres?to represent atoms and sticks to represent chemical bonds. The advantage of ball-and-stick models is that they show the correct angles between the bonds. However, the relative sizes of the spheres do not always match the relative sizes of the atoms they represent. ? ? ? 2.Space-filling models ? ? ? ? ?In real molecules, however, the atoms touch?each other. Both of these disadvantages are overcome with?space-filling models.?in which the spheres are drawn to scale and are next to one another?as atoms are in real molecules. The disadvantage of space-filling models is that the bond angles between atoms may be hard to see. ? ? ? ?3.Fullerene models ? ? ? ? ? Fullerene is the third isomorphic body found in elemental carbon. The structure of fullerene is similar to the?representative work of architect Fuller, so it is called fullerene. ? ? ?
