How Far Does the Periodic Table Go?

Efforts to fill the periodic table raise questions of special relativity that “strike at the very heart of chemistry as a discipline.”

How far does the periodic table go 1050x700

’Until December 2015, there were holes in the periodic table, elements synthesized but not yet officially recognized. But as we enter the International Year of the Periodic Table, the classic periodic table has been filled to its seventh row: In late 2015, the International Union of Pure and Applied Chemistry officially confirmed elements 113, 115, 117, and 118. The new elements also received their final names: nihonium, moscovium, tennessine, and oganesson. Efforts to find the next elements, 119 and 120, are underway.

Exactly how many elements are still to be discovered? Is there an end to the periodic table? When will we reach it? What does it teach us about the nature of the elements?…’
