The molecular model set is basically configured for some particular areas of study. They include crystal lattices, biochemistry, organic chemistry and stereo chemistry among others.

They include several types of components and permit building structures that are specific to the interest areas. Their main purpose is for educational purposes. They are a set of plastic bonds and atoms that enables the learners to construct space filing models of organic compounds and also to construct ball and stick structure.

It is divided into several divisions which they include the orbit molecular model sets that is meant for education especially in organic chemistry, lattices and in biochemistry.

 

When it comes to biochemistry sets, the learners’ molecular model set makes sugars, peptides, steroids, fats, glycerol, lipids, complex polysaccharides and reaction mechanisms among others. Crystal lattice structure set is also a division whereby the student molecular model set puts up seven main crystal systems and lattice structures like metals, diamond and graphite.

The molecular set encompass of molded balls with different sizes and different colors together with the connecting lugs of different sizes. They are very helpful when it comes to modeling different organic and inorganic compounds. The main set consists of one hundred and fifty lugs and three hundred and seventy balls while the minor set has only thirty lugs and seventy five balls of different sizes and colors. The crystal model set also consists of jacks and connectors of different colors that are joined in an illustrated way so as to form structure like diamond among others.

This has been exceedingly popular and is still widely used today.

 

At first atoms were made of spherical wooden balls with specially drilled holes for rods. Hence carbon atom can be presented as a sphere with four holes at the tetrahedral angles.   

A trouble with fixed bonds and holes is that systems with arbitrary angles could not be built. This can be overcome with flexible bonds, originally helical springs but now usually plastic. This also allows double and triple bonds to be estimated by multiple single bonds, as shown in picture. 

The balls have different colours: black represents carbon (C); red, oxygen (O); blue, nitrogen (N); and white, hydrogen (H). Each ball is drilled with as many holes as its conventional valence (C: 4; N: 3; O: 2; H: 1) directed towards the vertices of a tetrahedron.

Single bonds are represented by (fairly) rigid grey rods. Double and triple bonds use two longer flexible bonds which restrict rotation and support conventional cis/trans stereochemistry.
