Molymod Valence Shell Electron Pair Repulsion KitOrder code: MKO-VSEPR-14
The MolymodŽ Valence Shell Electron Pair Repulsion (VSEPR) kit is ideal for teaching about molecular shapes. Use the VSEPR kit to make linear, trigonal planar, tetrahedral, trigonal bipyramidal and octahedral structures plus at least14 VSEPR structures.
Coloured links represent electron-pair bonds (single, double and triple) and lone-pair electrons.
Includes atoms to make the following models:
metallic grey atom, 2 hole, linear, e.g. beryllium in BeCl2
yellow atom, 3 hole, trigonal, e.g. sulfur in SO3
black atom, 4 hole, tetrahedral, e.g. carbon in CH4
yellow atom, 4 hole, tetrahedral, e.g. sulfur in SO32-
red atom, 4 hole, tetrahedral, e.g. oxygen in H2O
light green atom, 4 hole, tetrahedral, e.g. fluorine in HF
light brown atom, 5 hole, trigonal bipyramidal, e.g. phosphorus in PCl5
yellow atom, 5 hole, trigonal bipyramidal, e.g. sulfur in SF4
green atom, 5 hole, trigonal bipyramidal, e.g. chlorine in ClF3
purple atom, 5 hole, trigonal bipyramidal, e.g. xenon in XeF2
grey atom, 6 hole, octahedral, e.g. metal complexes
brown atom, 6 hole, octahedral, e.g. bromine in BrF5
copper atom, 6 hole, octahedral, e.g. copper complexes
50 medium links (grey, single bonds)
15 medium links (purple, to represent lone pairs)
6 short links (white)
1 tool to disassemble models containing short link bonds.
The kit is supplied in a sturdy plastic storage box.
The MolymodŽ system is the original, unique, dual-scale system of high quality low-cost molecular models. They are ideal for school, university and research.
This product is not a toy, it is designed for educational use and is only suitable for students 12 years of age and over.
ACSSU186 - Chemical Sciences - Periodic table - The atomic structure and properties of elements are used to organise them in the Periodic Table
ACSCH056 - Molecular interactions and reactions - Intermolecular forces and gases - The shapes of molecules can be explained and predicted using three dimensional representations of electrons as charge clouds and using valence shell electron pair repulsion (VSEPR) theory
