Setting the table

Additions to the periodic table by synthesizing new elements has become almost routine, but The Economist reports,

"if all goes well, some time in the next few months will bring the creation of a new alkali metal, element number 119... . With that addition the table will do something which has never happened before. It will grow a new row."

That's Row 8 on the accompanying graphic.

Then, somewhere in the 120s might lie "the fabled island of stability".
