The ubiquitous periodic table will soon have a new addition - the "super-heavy" element 112.More than a decade after experiments first produced a single atom of the element, a team of German scientists has been credited with its discovery.
The team, led by Sigurd Hofmann at the Centre for Heavy Ion Research, must propose a name for their find, before it can be formally added to the table.
Scientists continue the race to discover more super-heavy elements.
Professor Hofmann began his quest to add to the periodic table in 1976.
The fusion experiments he and his colleagues carried out at the centre have already revealed the existence of elements with atomic numbers 107-111.
These are known as "super-heavy elements" - their numbers represent the number of protons which, together with neutrons, give the atom the vast majority of its mass.
To create element 112, Professor Hofmann's team used a 120m-long particle accelerator to fire a beam of charged zinc atoms (or zinc ions) at lead atoms. Nuclei of the two elements merged, or fused, to form the nucleus of the new element.
These very large and heavy nuclei are also very unstable. They begin to fall apart or "decay" very soon after being formed - within a few milliseconds, in this case.
This releases energy, which scientists can measure to find out the size of the decaying nucleus.
But such experiments produce very few successful fusions, and scientists need increasingly powerful accelerators to run experiments for longer and find the elusive, unstable elements.
This is why it took such a long time for element 112 to be officially recognised by the International Union of Pure and Applied Chemistry (IUPAC).
Its discovery had to be independently verified, and so far only four atoms have ever been observed.
IUPAC temporarily named the element ununbium, as "ununbi" is derived from the figures "one one two" in Latin; but Professor Hofmann's team now has the task of proposing its official name.
He is currently keeping the shortlist under wraps.

hmmm... couldnt they do this with just about any pair of stable elements? kind of like an easy bake oven for creating new elements?

All elements after 85 are synthetically created. And you don't have to wait to actually create an element before you name it, as you should already know most of its characteristics. So I'm suprised no-one has named it already.

Not all of these new elements heavier than uranium will be so alienly unstable.
By the way, there's a whole other bloc on an expanded periodic table - the g-block. Holy shit.
I dunno I just think this is sort of cool. I had to take a chemistry class.

Since it's very heavy and unstable, I would suggest the name Limbaugh 112.

someone please let me know how this doesn't qualify as creating your own elements. how could this element exist on its own in its own natural state?
thanks.

Isn't this the element bob lazar claimed he was working with in area 51? it was to do with the flying saucer propulsion system or something.
if it wasnt 115 it was one of the "super heavy" elements. I remember bob claiming it existed and then a few years later they actually discovered it! probably a load of twoddle

When I was a kid, they taught us that were 97 elements and that's it. There are no more.
Now we see how little we knewthen. However, this report also hints that this isn't the last element weither. Like science, knowledge expands. - 8 months ago

If this substance only occurs when made and lasts milliseconds I'm at a loss as to why it's an element..... I know Marie Curie had to work very diligently to extract radium from pitchblende.
Okay, it's a fundamental substance that consists of atoms of only one kind.
Since it's similar to mercury is it in liquid form? What are it's properties? I want more info.
Raz, is the picture with your story A new way to show the periodic chart or THE new way?
Gee, I'm ready to sign up for more chem. classes......
Very interesting, thanks for the info! - 8 months ago

Working together
Teams in Russia, the US and Japan are taking part in what Professor Hofmann described as the "friendly competition" to discover new, heavier elements.
In 2006, Professor Hofmann's competitors at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, claimed the discovery of element 118(Uuo on the chart above). It was made by bombarding a californium target with a beam of calcium ions.
"We have confirmed some of these results," Professor Hofmann told BBC News.
But he is now setting his sights higher. "We tried the same experiment to get to element 120. We've not seen it yet, but we believe the element exists and, with a long enough beam time, it could be produced," he said.
"It's certainly a race, and it's nice to be first."

Well if you start judging an element on how long it lasts it becomes entirely superficial. Geologically there are tons of elements that last for a sneeze. But since we only live for a trillionth of a geological sneeze we think they last for ages.
If it can exist it is an element. Now you should NEVER assume something can exist until you've been able to examine it in existence.
Course then again...that hasn't stopped millions of people. But I'm digressing.

I get it, just that most occur naturally and we know them in their natural state. At least we see them that way.
I was just being sarcastic about the short existence, didn't somebody, Nielson or harry, do a song about short existence? No that was short people. - 8 months ago
