It's been discovered alongside elements 113, 117 and 118. It has yet to be named; it currently has the placeholder name "Ununpentium".

Extracts from the article:

Four new elements have been added to the periodic table, finally completing the table’s seventh row and rendering science textbooks around the world instantly out of date.

...

IUPAC announced that a Russian-American team of scientists at the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California had produced sufficient evidence to claim the discovery of elements 115, 117 and 118. ...

...

The elements, which currently bear placeholder names, will be officially named by the teams that discovered them in the coming months. Element 113 will be the first element to be named in Asia.

...

“IUPAC has now initiated the process of formalising names and symbols for these elements temporarily named as ununtrium, (Uut or element 113), ununpentium (Uup, element 115), ununseptium (Uus, element 117), and ununoctium (Uuo, element 118).”

..

The four new elements, all of which are synthetic, were discovered by slamming lighter ­nuclei into each other and tracking the following decay of the radioactive superheavy elements.

Like other superheavy elements that populate the end of the periodic table, they only exist for fractions of a second before decaying into other elements.

Haven't those elements been on the periodic table for some time now?

Only as placeholders. It's now actually been synthetically created and observed, i.e. discovered. Edited the topic title for clarity

They should let us decide the name for the 115.

Ah OK makes sense.

Ununpentium has been referenced in a ton of media. Including the original star trek series ( 1960s ) - also referenced in some media related to call of duty ( mainly to do with shangrila )

Theoretically before hand, but likely the names for "future" elements to be discovered are already named, or like mentioned, just placeholders ( id imagine elements etc would be named after the person who discovered them ultimately )

its mentioned in transformers too, as a "unbreakable metal" - however this actually makes no sense as pointed out by the fans lol

They should let us decide the name for the 115.

Divinium (DUH)

Divinium (DUH)

no even in cods universe its called Ununpentium already...

divinium isnt explained, but im gonna assume itll be boiled down to some kind of liquid created "using" Ununpentium ( judging  by its blue colour compared to 115 in origins )
