But deep down inside, probably everybody believes there is an internal order that the periodic table represents, a fundamental truth that is the bedrock of chemistry.

The periodic table orders all the elements in neat rows and columns as a guide to their properties and atomic structures. Atomic structure, in fact, explains why the periodic table works, but this ...

What elements have recently been added to the periodic table and how are new ones discovered? Can you give some examples of any particularly interesting ones?

Is It Time to Upend the Periodic Table? The iconic chart of elements has served chemistry well for 150 years. But it’s not the only option out there, and scientists are pushing its limits.
