IUPAC’s confirmation of four new elements, 113, 115, 117 and 118, was announced a couple of days ago with very little fanfare, and in the process, period 7 of the periodic table was completed!
Of course, if you happen to follow my blog, you’ll know that back in July of this year I wrote this post which predicted the same. If I’m honest, I was a little surprised that all four were ratified by IUPAC, especially 118, but as you can see from that earlier post, not entirely.
The Japanese team at RIKEN only gets 113, and the other new elements are jointed accredited to the Russian and American collaborations.
Now we go to the naming stage, and my July post has a few predictions for the RIKEN accredited element. I suppose I should now have a guess at some names and symbols for all four, although that little task will be a lot more hit and miss than the original predictions. If you’d like to read more about the naming process and what is and isn’t acceptable, take a look at this document. It’s actually surprisingly approachable and readable (if you’re into that sort of thing), and isn’t too long.
Anyway, I suppose the search of 119 is now being accelerated – who knows, maybe in another few years we will start period 8 and maybe Q8 from the 2006 AP Chemistry Exam will seem just a little more real!
