Oganesson, named for Russian physicist Yuri Oganessian (SN: 1/21/17, p. 16), is the heaviest element currently on the periodic table, weighing in with a huge atomic mass of about 300.

Oganesson is a radioactive, artificially produced element about which little is known. It is expected to be a gas and is classified as a non-metal. It is a member of the noble gas group. The ...

Meet nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og), the newest elements on the periodic table to receive names. But don’t get too attached to the nomenclature for these ...

Four new elements are about to be added to the periodic table: nihonium (Nh, element 113), moscovium (Mc, element 115), tennessine (Ts, element 117), and oganesson (Og, element 118). When you say ...

Oddly, though, at temperatures between these two, the element doesn’t react. Oganesson is grouped in the periodic table with the noble gases, but researchers think it is neither noble nor a gas.

Oganesson is the second element named for a living person; the first, seaborgium, was named in 1997 after American physicist Glenn Seaborg two years before his death.

Oganesson, that element at the bottom right of the periodic table, has 118 protons. The only isotope of it we have managed to make has 176 neutrons, for a combination of 294 nucleons, the main ...

Oganesson: Element 118. Oganesson (Og) is the most recently added superheavy element (SHE) in the periodic table. It ...

Oganesson and symbol Og, for the element 118; The new superheavy, radioactive elements were actually added to the periodic table late last year and given these temporary and unremarkable names: ...
