Four New Elekents Have Been Added to the Periodic Table - Amar Toor/ Science/ theverge.com.

"Four new elements have been permanently added to the periodic table, after their discoveries were verified by the global chemistry organization that oversees the table. The International Union of Pure and Applied Chemistry (IUPAC) last week announced that elements 113, 115, 117, and 118 have met its criteria for discovery, making them the first elements to be added to the periodic table since 2011. Their addition also completes the seventh row of the periodic table..."

Of course, these new superheavy elements decay very very fast ... almost as fast as a timeshare salesperson's scruples

He's 87 and still kicking, so maybe Tom Lehrer will write another verse.

wonder what the half-life of a scruple is.........

When Will We Reach the End of the Periodic Table? by Devin Powell/ Science/ Nature/ SmithsonianMag.com

"Even with new elements in hand, scientists are struggling to predict the future of the iconic chemical roadmap.

Chemistry teachers recently had to update their classroom décor, with the announcement that scientists have confirmed the discovery of four new elements on the periodic table. The as-yet unnamed elements 113, 115, 117 and 118 filled in the remaining gaps at the bottom of the famous chart—a roadmap of matter’s building blocks that has successfully guided chemists for nearly a century and a half.

The official confirmation, granted by the International Union of Pure and Applied Chemistry (IUPAC), was years in the making, as these superheavy elements are highly unstable and tough to create. But scientists had strong reason to believe they existed, in part because the periodic table has been remarkably consistent so far. Efforts to conjure up elements 119 and 120, which would start a new row, are already underway.

But exactly how many more elements are out there remains one of chemistry’s most persistent mysteries, especially as our modern understanding of physics has revealed anomalies even in the established players.

“Cracks are beginning to show in the periodic table,” says Walter Loveland, a chemist at Oregon State University..."
