Elements Old and New
Discoveries, Developments, Challenges, and Environmental Implications
ACS Symposium Series

The Periodic Table of the Elements remains a living, growing document that attempts to map out all of the most primal matter known to humankind. This book preserves our current knowledge and understanding of the Periodic Table of the Elements as it exists at this specific moment in time. The heavy elements have recently been verified and named, and thus complete the seventh row of the Periodic Table, with oganesson being the name of the final element, which had formerly been known as Element 118 or Eka-radon. One can say honestly that it is a rare moment in time when a row of the Periodic Table of the Elements is completed.
