About LINKTOR Chemistry Molecular Model Kit, Student Or
Our amazing chemical molecular model contains 78 atoms, 111 chemical bonds. 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. Our guarantee If you have any doubts, please let us know by email.
