Chemical4
The heavy element chemistry program conducts unclassified basic research on all the actinide and transactinide elements, while the applied programs generally limit their investigations to the chemical and material properties of specific elements and systems of strategic, economic, or programmatic interest. (docslib.org)
It continues today as the nation's only basic research program supporting the exploration of the physical and chemical properties of the transuranium elements and their compounds. (docslib.org)
The chemical properties of the transuranium elements, especially plutonium, originally were determined from microscale experiments. (docslib.org)
For the elements heavier than Es in the periodic table, tracer techniques and one- atom -at-a-time chemistry have been developed and carried out through element 108 to determine chemical properties. (docslib.org)
