Was I the only middle school student forced to learn the whole periodic chart? I guess it still comes in handy occasionally, and my memory hasn’t failed me yet, I still can recite the entire chart. But that may change soon.

Scientists quietly sneaked in a couple of man-made elements to the chart, and although they have not officially been named; they’re being called: Ununtrium, ununpentium, ununseptium, and ununoctium, also known as elements 113, 115, 117, and 118.

“The 7th period of the periodic table of elements is complete,” says the International Union of Pure and Applied Chemistry. Russia and the U.S. both ‘discovered’ element 118, while Japan took credit for 115 and 117. When it comes to naming the elements the unions says they’ll use “a mythological concept, a mineral, a place or country, a property or a scientist.”

Guess it’ll be time to update the science books in schools.
