their electrical attractions. Some grouped together to form molecules of gases that
became the atmosphere; others joined in compounds but retained fluid mobility in the
waters of the ocean. Others joined together in the fixed positions of solids. Each
mineral has a unique crystalline structure that will distinguish it from another
mineral even if the two are composed of the same element or elements. Consider the
minerals diamond         and graphite, for example. Other minerals may have more
complicated crystalline structure; they may contain more elements and have them
joined together in more complex patterns. The color, shape and size of any given
material may vary from one sample to another, but the internal atomic arrangement of
its component elements is identical in all specimens of a particular mineral.
