1R50.30 - Crystals, Crystal Structure, Atomic Planes, & Metals

Code Number:
1R50.30
Demo Title:
Crystals, Crystal Structure, Atomic Planes, & Metals
Condition:
Excellent
Principle:
Crystal Formation and Structures
Area of Study:
Mechanics

Disclaimer

Equipment:
Crystal Samples.
Procedure:

See also 4A10.50 in Heat and Fluids and 6H35.62 in Optics.

A large variety of different crystals are available.  Do Not Shake the crystal samples when they are in the boxes to much as this will break off some of the corners etc.  Keep the samples in a dry place as some of the crystal will dissolve in water (ie. Copper Sulfate).  Some very large crystals are also available.

The packing foam comes in several different structures and can be used to represent crystal structures in atomic planes.  This should be similar to what is seen with an atomic force microscope.

Atomic nuclei of any atom can be built with the Atomic Structure kits.  Two nuclei are shown which are Uranium 235 with its 92 protons (orange) and 143 neutrons (light green) and Helium with two protons (red) and two neutrons (blue).
