Earlier today someone asked the question, In a mass knife fight to the death between every American President, who would win and why?

4 New Elements Complete 7th Row of Periodic Table

‘…The International Union of Pure and Applied Chemistry has verified the discovery of four super-heavy elements, completing the seventh row of the periodic table. It’s an exciting day for chemists.

The new elements were discovered by teams of scientists from Russia, Japan, and America. These will be the first elements added since 114 (Flerovium) and 116 (Livermorium) were added to the table in 2011.The trick to “finding” these elements isn’t so much in searching for them as it is in creating them. The new elements, given the atomic numbers 113, 115, 117, and 118 are synthetic — they do no occur naturally.

…Eventually, the laws of physics may halt the progression of creating new elements. But for now, there are four new elements that need proper names. The IUPAC will formally announce the finalized names this summer….’
