4 new elements Nh, Mc, Ts and Og

[BobL]

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.

Wow, awesome. When was the last time we got a new element? I don't recall this happening since I started studying science.

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.

More recently;
112 Copernicium Cn 2010
114 Flerovium Fv 2011
116 Livermorium Lv 2011

Sorry that link doesn't work as you need special access rights.

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!

[Bushmiller]

I guess it would be difficult to label them. Just these tags and nothing in the loop of string .

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 18
have some fun exploring Dynamic Periodic Table

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?

[BobL]

Has Mendeleiev himself been honoured in this process?

Element 101 is named after him.

The new names and symbols are not yet official - the names are open for public comment for 5 months and changes may be made if they are found to breech technical issues regarding the naming of elements.

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.
