The International Science panel I've been on for the last couple of decades has just named 4 new elements nihonium, moscovium, tennessine, and oganesson.
See http://iupac.org/…/Press-Release_Naming-Four-New-Elements_8…
It's not often we get 4 new ones announced at the same time.
There's hope for unatanium yet
Sorry, couldn't resist that one
On a serious note, there is more stuff waiting to be found than that which we are already aware of
I believe it it the first time they have named new element after a living scientist. Oganesson recognises Yuri Oganessian.

Nor quite, Its the second one, Seaborgium was alive when Seaborgium was proposed.Quote:

And how about that Tennessine? Named after the greatest state of the fifty!
Have to update the t shirt to McBaCON
There have been 1 or 2 every few years - Its the first time we have had 4 at the same time for many years.Quote:

I co-wrote the official recommendations for the last 2

How long do these elements exist for, Bob? I suspect they are very ephemeral.
You are right , Micro/Milliseconds. What amazes me is that in that time they are able to even do a a bit of chemistry!Quote:

So is someone updating the atomic table to incorporate the new elements? Just wondering where they would fit
here you go they're in Row 7, in Columns 13, 15, 17 and 18Quote:

Oh no! Now there are thousands of kids who'll have to relearn the periodic table song :(
And some parents ...
Has Mendeleiev himself been honoured in this process?
Element 101 is named after him.Quote:

So don't write to IUPAC and tell them you want the names changed to include the name of your cat, your dad or your favourite fictional character (yes we have received these requests in the past) :)
Minor technical issue, About a dozen elements no longer have a single atomic weight because the atomic weights for these elements are sample dependent. Their atomic weights are now expressed as an interval e.g. Li [6.938, 6.997]
If you want to perform accurate chemical calculations the atomic weight of the element in the sample must be measured.
To make things simpler for the average Joe and school kids, a table is provided known as a representative atomic weight table so the only have to deal with a single number.
