Shape Of Seven Crystals  [201.225]
 

These modles clearly explain how basic 7 types of crystals look like and why they differ with each other. You can measure the angle & axes like a=b=c etc. You can explain the centre of symmetry also in each crystal.

a) Cubic
b) Rhombohedral
c) Orthorombic
d) Triclinic
e) Tetragonal
f) Hexagonal
g) Monoclinic

Sizes of thses modles vary between 8cms & 15cms.

Modles of flourite, rutile, Zinc Blende, Wurtzite, Calcium Carbide, Boron, Nitride are also available.
 
Atomic & Hybrid Orbital Models Set  [201.228 CH]
 

The Marvellous set of Orbital Models offer an easy 3 dimensional approach to the Quantum Machine & its application to chemical bonds. these are bright, large, colourful and strdy.

The unique advantages of our model are :
(a) the perfect shape of each of each orbital can be shon
(b) The positive & negetive region of the orbital are indicated with the shade of colour
(c) the cross section of orbitals to pinpoint the inner orbital region, nodal planes & probable electronn regions
(d) The convenience of splitting the model into the halves to show nucleous.

Simple Inorganic Molecule Kit  [201.229 CH]
 
The basic Concepts about the Principles of molecular shape made easy...This kit offers a lot of 3 dimensional Models with a visual appreciation of Molecular Bonding. You can demonstrate how the shapes of Molecules are determined by the number of bonds plus the lone pairs in the velence shell of the centre atom. Showing lone pairs a unique speciality with these models. To show the molecule based on tetrahedron you can make methane, for triagnal bypyramid, you can make phosphorus phosphours pentachloride; and for octahedron you can build sulpher hexa flouride and soon.
Some Of The Structures : CO
