4 New Elements Have Been Added To The Periodic Table -- Which You Totally Memorized, Right?

Memorize these and impress people by pretending you know chemistry.

Four brand spankin' new elements have been discovered and added to their rightful place on the seventh row of the periodic table, according to the International Union of Pure and Applied Chemistry (IUPAC).

While this is no doubt satisfying to people who like to see non-rectangular shapes live up to their full rectangular potential, it's also a great day for chemistry geeks everywhere as the elements 113 (ununtrium, Uut), 115 (ununpentium, Uup), 117 (ununseptium, Uus) and 118 (ununseptium, Uus) were added into the seventh period of the table.

Ooh. Nice.

As these elements (all of them synthetic) are "super heavy," The Guardian reports they tend to only exist for "fractions of a second before decaying into other elements." They were discovered "by slamming lighter ­nuclei into each other and tracking the following decay of the radioactive superheavy elements."

These four elements -- the first to be added to the table since 2011 -- were discovered by scientists in Japan, Russia and America and verified by IUPAC on December 30, 2015. Though they're considered full-fledged elements, they still have some less-than-sexy unofficial "working" names and symbols, but IUPAC officials say they are well on their way to being officially christened as elements in the next five months.

Giphy

"The chemistry community is eager to see its most cherished table finally being completed down to the seventh row," Professor Jan Reedijk, President of the Inorganic Chemistry Division of IUPAC, said in a press release. "IUPAC has now initiated the process of formalizing names and symbols for these elements..."

The bad news? All of your textbooks and all the cheese-tastic educational videos from your youth are now super obsolete. Bummer.
