They illustrate topics such as why chemical bonds are formed, the bonding mechanism, configuration of orbitals on atoms, sigma and pi bonds, types of bonding like covalency, polar covalency, electrovalency, metallic bonds. Etc.  These are useful for students from grade 9 to 12 as well as general public.  More such exhibits will be added in future.
