This set is the same as “The Prentice Hall Molecular Model set for Organic and Inorganic Chemistry“, with 12 additional atoms (1 carbon, 2 hydrogen, 2 oxygen, 2 fluorine, 2 sulfur and 3 phosphorus) and 20 additional single bond (space filling) and 20 additional single bond (open model) and 13 additional double/treble bond (open model) and 4 additional coordinate/covalent double bond (open model).  It can be used to build virtually all simple molecular models encountered in organic and inorganic chemistry.

This set includes 240 pieces of durable and fine quality plastic components, virtually indestructible, and come in a sturdy plastic case for storage.

1.All shape and measurement of spherical atoms (some of them may not be included in this set) :

2.Four types of links :

• single bond, space filling model, 1mm length, white color or transparent
• single bond, open model, 20mm length, grey or purple color
• double or treble bond, open model, 35mm length, gre y or purple color
• single bond, “V” shape, open model, 3mm length, white color
