Chemistry Molecular Model Kit (239 Pieces), Student Or Teacher Set For Organic And Inorganic Chemistry Learning, Motivate Enthusiasm For Learning And Raising Space Imagination

Our amazing chemical molecular model contains

86

atoms,

153

chemical bonds and

a

disconnector tool, with a total of

240

parts. Particularly suitable for beginners in chemistry and high school teaching of

Inorganic Chemistry

,

Organic Chemistry

and

Structural Chemistry

.

There are two 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.
