Additional Elements

Dale Mais has contributed 20 new elements to our Element library.  These elements are just the more common and generally easy to identify. The oddest one may be technetium (#43) because it has no stable isotopes. As a result it is not found on earth (the longest lived isotope is ~2 million years), yet it is very well observed in Carbon and S type stars which means it is being made and dredged up to surface.

There many types of stars with very peculiar abundances of some elements (such as Strontium stars or barium stars or cobalt stars.) There are some stars that have peculiar combinations of elements (chromium/europium, manganese/mercury, etc). Many of the others are easy to find so they were included.

To add these elements to RSpec, unzip to the Documents\RSpec\ElementsCustom folder.  Download link.
