The International Union of Pure and Applied Chemistry announced names for the four newest elements on Wednesday, Nature reports. Those names: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og). According to the Guardian , elements... More »

7th Period of Periodic Table Is Now Complete

Establishing Element 113 involved some heavy competition, more than a decade

(Newser) - As the International Union of Pure and Applied Chemistry puts it in a press release , "The 7th period of the periodic table of elements is complete." It has verified the discovery of elements 113, 115, 117, and 118, effectively filling the 7th row and "rendering science textbooks... More »

Scientists Make a New Element

Element 117 is heaviest ever

(Newser) - Scientists in Germany have created atoms of a new element, they say: element 117, the heaviest metal ever made, Gizmodo notes. The element, like all those with atomic numbers beyond 104, isn't found naturally and must be made in a lab, Live Science notes. Ununseptium, as the new element... More »

Gold, 18 Elements Get a New Atomic Weight

Along with 18 other elements

(Newser) - Scientists made a weighty announcement this week: 19 elements on the Periodic Table, including gold, arsenic, and aluminum, have been assigned new atomic weights. Remember the glory days when cadmium was 112.411(8) atomic mass units? No longer. The International Union of Pure and Applied Chemistry says it's now... More »

Super-Heavy New Element Set to Join Table

Scientists say they've confirmed element 115

(Newser) - After weeks of blasting the element calcium with the element americium, scientists say they've confirmed the existence of the 115th element. The super-heavy new element—called "ununpentium" after its atomic number for now—was first proposed by Russian scientists in 2004 but has yet to be added to... More »

Now on the Periodic Table: Livermorium

...Flerovium, too

(Newser) - Nearly a year after they joined the periodic table, two man-made elements have been officially named. What used to be element 114 is now flerovium, honoring the Flerov Laboratory of Nuclear Reactions in Dubna, Russia, where it was created. Element 116 is now livermorium, for the Lawrence Livermore National Laboratory... More »

New Elements Fl, Lv Named

Heavy elements flerovium and livermorium closer to joining the club

(Newser) - You can pencil two new elements onto your periodic table, because prospective elements 114 and 116 have finally gotten names. The International Union of Pure and Applied Chemistry today dubbed the two elements flerovium (Fl) and livermorium (Lv) respectively, MSNBC reports. But do use pencil, because the names aren’t...

Scientists Spot Gas Clouds That Seeded All Life

Early formation created stars that led to our own

(Newser) - Astronomers have caught a first-ever glimpse of gas clouds as they existed just a few minutes after the big bang, the Los Angeles Time s reports. These clouds—long gone by now, but still visible to us—contain lighter elements like hydrogen and helium, which condensed into stars during the... More »

New Theory: Earth Once Had 2 Moons

A collision might explain the moon's asymmetry

(Newser) - The sky above Earth may once have been a little more crowded. The planet originally had two moons that collided into one, according to a new theory proposed in Nature . It's widely believed that the early Earth collided with a Mars-sized proto-planet, and that debris coalesced into the moon.... More »

How to Expand the Periodic Table

Step one: Make your own element

(Newser) - With two new elements on the periodic table this month, NPR offers a step-by-step tutorial on how you, too, can add an element—if you’ve got an atom-smashing device lying around. First, you have to make a new element by slamming atoms of two elements together and hoping their... More »

Periodic Table Gets 2 New Elements

Still unnamed, numbers 114 and 116 have been approved as chemical elements

(Newser) - Two new chemical elements have been officially added to the periodic-table torment of high school kids everywhere. But as-yet-unnamed Nos. 114 and 116 aren’t like their new buddies carbon, gold, or zinc—they were created by slamming two lighter elements together in the hopes they’d stick, said a... More »

Periodic Table Adds Element

Copernicium (Cn) checks in at No. 112

(Newser) - Fourteen years after its discovery, a new element has been added to the periodic table. Copernicium (Cn) will take its place as element number 112 after a long dispute over naming. The leader of the victorious German team said he picked Copernicus to “salute an influential scientist who didn’... More »
