The Molymod® VSEPR (Valence Shell Electron Pair Repulsion) set can be used to make a considerable number of molecules but in particular to make models to display at least 14 VSEPR structures. It is ideal for learning about the basics of molecular shape. You can make models that represent linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral shapes. Coloured links represent electron-pair bonds (single, double, and triple) and lone-pair electrons.

• Atom parts are made of solid coloured plastic spheres.
• They are available with from 1 - 6 holes in the usual angular orientations.

Contents of the VSEPR Molymod® molecular models kit

The contents are contained within a sturdy plastic storage box.

Atoms

Enough central atoms are included to make the following models

• metallic grey atom, 2 hole, linear, for instance beryllium in BeCl₂
• yellow atom, 3 hole, trigonal, for instance sulfur in SO₃
• black atom, 4 hole, tetrahedral, for instance carbon in CH₄
• yellow atom, 4 hole, tetrahedral, for instance sulfur in SO₃^2-
• red atom, 4 hole, tetrahedral, for instance oxygen in H₂O
• light green atom, 4 hole, tetrahedral, for instance fluorine in HF
• light brown atom, 5 hole, trigonal bipyramidal, for instance phosphorus in PCl₅
• yellow atom, 5 hole, trigonal bipyramidal, for instance sulfur in SF₄
• green atom, 5 hole, trigonal bipyramidal, for instance chlorine in ClF₃
• purple atom, 5 hole, trigonal bipyramidal, for instance xenon in XeF₂
• grey atom, 6 hole, octahedral, for instance metal complexes
• brown atom, 6 hole, octahedral, for instance bromine in BrF₅
• copper atom, 6 hole, octahedral, for instance copper complexes

Bonds

• 50 medium links (grey, single bonds)
• 15 medium links (purple, to represent lone pairs)
• 6 short links (white)

Tool

• 1 tool (used for disassembling models containing short link bonds)
