The classic design of the table was created by Dmitri Mendeleev in 1863, organizing the then-known elements by number of electrons. Inspired by a graphic that sized the elements to reflect their ...

Still using an old science textbook? It's time to get a new one then, after four new super-heavy elements were added to the periodic table recently. The International Union of Pure and Applied ...

The elements formerly known as 113, 115, 117, and 118 have been officially named Nihonium (Nh), Moscovium (Mc), Tennessine (Ts), and Oganesson (Og), respectively. With this confirmation, they can join ...

Remember your periodic table from high school chemistry? As of Monday, it will look a little different. Four new elements have been added to the tail end of the familiar chart, completing the seventh ...

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. This is ...

Two scientists in Moscow have proposed replacing the periodic table as the chief way to organize elements. Rather than ordering by atomic number (the number of protons in the nucleus) the chart lists ...

The periodic table - the chart studied by generations of children and chemists - is to get a little more crowded. Scientists yesterday announced they are to add a 'super heavy' element, called ...

Six atoms may seem minuscule–especially if they exist for only fractions of a second–but they can have huge implications. The recent announcement that Russian and American scientists finally managed ...

Kosuke Morita (L), who led the team at Riken institute that discovered the superheavy synthetic element, and Hiroshi Hase (R), Minister of Education, Culture, Sports, Science and Technology, pose with ...
