Description:
This is a mineral molecular model representing the crystalline arrangement of iodine molecules (I2) with brown spheres that are made of a plastic material, and held together by brass rods. The brown spheres are changing color and they are gradually turning into an olive green shade.
Notice that only pairs of atoms are linked by rods.
The model is mounted on a base of plywood with a reddish-brown varnish. It has a paper label glued onto it.

Historical AttributesThis molecular model is part of a group in the Collection that were made by Harvard students for courses in geology and mineralogy between the early 1950s and the early 1970s. Some of the molecules were simple class assignments, whereas others are more complex and refer to recent publications. They remained in the Geology Department for display and instruction.
