Molecular Models
Stretch your budget dollars with these low cost, highly effective hands-on models
Research shows that concrete representations of abstract concepts increase student understanding, retention and interest. Our economy line of bonding models was designed to bring fundamental chemistry concepts into focus at an affordable price. Students will easily grasp the typical arrangements of elemental particles when handling these sturdy, brightly colored plastic balls which have been permanently mounted in their correct atomic orientation.
Iodine- T22016
This model demonstrates the typical arrangement of bi-atomic molecules such as I2 or O2.
Diamond - T22005
Diamond is the world's hardest natural substance. Your students will be able to understand why when they view the arrangement of carbon atoms represented in this model.
Silicon Dioxide - T22010
Show the structure of silicon dioxide and other covalent compound by demonstrating the tetrahedral-shaped arrangement of their particiles.
Sodium Chloride - T22003
This versatile model demonstrates the ion lattice crystal of the sodium chloride type such as NaCI, NaBr, AgCI, MgO and CaO.
Caesium Chloride - T22015
Illustrates the ion lattice crystals of the caesium chloride type such as NH4CI and CsCI using this model.
Metal Lattices
Demonstrate the three most common particle arrangements in metal lattices. Used alone or as a set, these are sure to help "crystallize" your students' understanding.
Hexagonal Maximum-Denisty Lattice - T22006
Cubic Spatially-Centered Lattice - T22007
Cubic Surface-Centered Lattice - T22002
These top quality instructor versions enhance the classroom experience.
The large size and careful construction of these demonstration models allow you to illustrate typical crystal structures to the entire class at once! Designed to be visible from any point in the room, they can be rotated and viewed from any angle to show the beautiful and complex arrangement of atoms in these naturally occurring substances.
Calcium Carbonate - T22013
This model demonstrates the elementary structure of calcium carbonate (calcite) as well as other crystal structures of similar construction.
Graphite - T22004
Use this unique model to illustrate the structure of graphite with its tightly packed carbon atoms arranged in layers. The clear plexiglass surfaces which separate the layers provide an unobstructed view of the dark carbon ÓatomsÓ and help students to understand how this arrangement explains graphites physical properties.
Calcium Sulphate - T22001
Use this model to show the elementary structure of calcium sulphate (anhydrous) as well as other comparable crystal structures such as silicate and phosphate. The bonds of the elementary structure are identified in white so as to be clearly visible.
Hydrogen Bridge Bond - T22012
Hydrogen bonds represent some of the most common and important secondary bonds. Use this model to illustrate the hydrogen bonding found in ice, water, acetic acid or HF2.
Carbon-Carbon Bond - T22008
This set consists of orbital models of ethane, ethylene, acetylene, and benzene molecules representing the sigma and pi bonds found in carbon-carbon pairs
