New element names proposed

[Vandal]

Say Hello To Your Four Newly Named Elements Of The Periodic Table

Looks like it’s nearly time to update that old periodic table poster on your wall. Because names have been proposed for four new elements announced in January and, provided there are no objections, the names could be ratified in five months by the International Union of Pure and Applied Chemistry (IUPAC).

The names correspond to the newly discovered elements that occupy positions 113, 115, 117, and 118 in the table, completing its seventh row. In order they are Nihonium (Nh), Moscovium (Mc), Tennessine (Ts), and Oganesson (Og). Sadly, there’s no Element McElementface.

As is tradition with new elements, the discoverers get to pick the name. Nihonium, discovered at the RIKEN Nishina Center for Accelerator Science, refers to the Japanese name for Japan, Nihon. Moscovium refers to Moscow, where it was found at the Joint Institute for Nuclear Research in Dubna.

Tennessine refers to the US State of Tennessee, the location of the Oak Ridge National Laboratory and Vanderbilt University where it was found. Last but not least is Oganesson, which refers to nuclear physicist Yuri Oganessian, who led the research for this element and others.

Is matter evolving into new elements or have these always been around waiting to be discovered?

If they ever did exist it was for only a few picoseconds or fewer at the time of the Big Bang.

I guess you're going to have to keep waiting for Vandalium.

How about adamantium?

In order they are Nihonium (Nh), Moscovium (Mc), Tennessine (Ts), and Oganesson (Og).

Interesting that two of those new element names don't end with -ium. That means radon (#86) would no longer be the highest numbered element that doesn't end with -ium.

I guess I understand it for Tennessee because the construction would be linguistically awkward. But for Oganessian I don't see why they wouldn't go with Oganessium.

Having said that, haven't elements usually been named for more prominent scientists? --Bob

Element 117 is in the halogen group of the periodic table (fluorine, chlorine, etc.) and element 118 is in the inert gas group (argon, radon, etc.). Not that there will ever be large enough samples of these elements to display the chemical properties of those groups.

Here's Oganessian's biography. Apparently, he's a big shot in Russia and in heavy element physics.

Yesterday's answer: The Lounge. BTW- The other secret passage
connects the kitchen to the study. I can always remember this
because the same room set-up was used in the 1985 movie,
which even after seeing 30+ times still has me ROTFL!

Today's question:

Of all the elements which are gases at room temperature, which
has the highest atomic number?

I think it's Radon.

Radon, unless I change my mind later

I can use one point- Radon

Not to be a booger about this, but the answer is probably a lot
more funky than you intend it to be. The highest known element's
atomic number is 118, for an unnamed element which is a noble
gas and which was synthesized at Berkeley. They created a total
of three atoms of this "stuff," which almost immediately
decomposed to element 116, which is also unnamed. They
created this stuff by fusing other atoms (I think krypton and lead;
maybe they should call it kryptonite), in order to make a new,
previously unknown element.

In the real world (the world outside of California) the highest
atomic number for an element that is a gas at room temperature is
radon.

Are we sure thst element 118 existed in a gaseous state? Being
in the Noble Gasses is not sufficient, in my mind. If they created
only 2 atoms and it almost immediately decomposed, how were
they able to determine any properties? Especially at room
temperature. The fusion on two elements requires some pretty
extreme conditions. Seems as the sample size was too small
and too unstable for any accurate observations. I do not believe
it ever achieved "Room Temperature".

The fundamental principal underlying the Periodic Table is that
you can predict the properties of an element simply based upon
where it falls on the table; that would indicate that anything that
falls in the column of noble gases must be a gas at room
temperature.

But you are right, Eyegor, about the extreme conditions needed
to create element 118 (which I would REALLY like to see called
"kryptonite"): they had to fire particles accelerated to an energy
level of over 400 million electron volts, they created about one atom
for every trillion interactions, and it lasts about as long as a
politician's promise (about a fifth of a millisecond); which is why
element 118 is a "booger" answer. But still, technically, I think it is
the right answer (I am SURE it will come up on WWTBAM
someday...)

I agree that that is the principal. But the periodic table was
devised based upon the observations of the known elements
(and has held up remarkably well). However, without empirical
data, I respect that you chose to pick the "booger" (blech!), but
I have to stick with Radon.
