(More customer reviews)I am piecing together covalent bonds (nonmetal+nonmetal) for my Chem 101 class as I write this review and all I can say is this is a really nice set. I am so glad I bought this particular set (I shopped around and most were over-priced or poor quality). If you are having problems with Lewis Bond structure, this will definitely help you. The set states that "Atom models are made of solid colored polyethylene." I have about 4 more chemistry classes to go and this is a very good investment. It comes with 28 hydrogen, 14 carbon, 8 oxygen, 2 fluorine, 2 bromine, 8 chlorine, 4 nitrogen (3 valence), 1 nitrogen (4 valence), 2 sulfur, 2 phosphorus, 2 iodine, 40 links for single bonds and 12 links for double bonds. This is a pretty sturdy set and comes in a case with compartments so you can carry it to school. Glad I bought it!

Organic Chemistry Molecular Model SetTHE ORGANIC CHEMISTRY MOLECULAR MODEL SETThis economical model set has the same number and types of atom models as The Prentice Hall Molecular Model Set PLUS seven extra atoms: 2 sulfur, 2 phosphorus, 2 fluorine and 1 nitrogen with 4 valence electrons. The flexible links allow you to create single, double, and triple bonds. The model building instructions include pictures that show how to assemble the atom models. This set contains 125 durable plastic components that can be used to build thousands of molecules. It is the perfect size to carry in your backpack or purse. The snap-closure prevents spills and the compartments keep the atom models and bonds conveniently separated. When learning to visualize 3-D molecular structures, isomerism and nomenclature, this model set is essential. This set contains 125 pieces:14 black carbon atoms28 white hydrogen atoms 8 red oxygen atoms 4 blue nitrogen atoms with valence 3 1 blue nitrogen atoms with valence 4 2 green phosphorus atoms 2 yellow sulfur atoms 8 green chlorine atoms 2 yellow fluorine atoms 2 orange bromine atoms 2 purple iodine atoms12 gray links for multiple bonds, 40 mm40 gray links for single bonds, 25 mmPlastic case (21 x 11 x 3.5 cm) Instructions Included.
