Chemical Names & the Elements What's in a (Chemical's) Name? : Why some names are more contentious than others? Who does, and who should have the final say in approving names? What names you might have chosen for elements , and why? Why it might matter for everyone around the world to use a common name for the elements?

History of the Elements alchemy---philosophers stone turns lead into gold Today with nuclear technology we can transmute lead into gold The periodic table has been very useful in predicting elements before they are found Nuclear isotopes ---more neutrons Search for the super heavy elements and the issue of nuclear stability as the nucleus size increases Many scientists think if we can get high enough we will find stable elements again—Dr. Glen Seaborg island of stability NIF ---Nuclear Ignition Facility CERN
