12, 2012, after colliding zinc nuclei together in a thin layer of bismuth. Like other superheavy elements, after 113 was created, it quickly decayed, ultimately turning element 113 into 111, and then 109, 107, 105, 103 and finally into element 101, according to Morita. Nihonium has six isotopes with known half-lives.
Is element 118 real?
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. In November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name oganesson for element 118.

Who made the Left-Step periodic table?
French scientist Charles Janet’s left-step periodic table, devised in 1928, isn’t likely to make it into textbooks anytime soon, however. Janet moves the s-block to the right side of the table and includes helium at the top of group 2 because its s orbital, like other elements in that group, is filled.
Who made the first periodic table?
In 1869, Russian chemist Dmitri Mendeleev created the framework that became the modern periodic table, leaving gaps for elements that were yet to be discovered.
Who created the 3D flower periodic table?
Brief history 1862: Alexandre Béguyer de Chancourtois publishes a 3D arrangement of the elements, the first to use a periodic arrangement, showing that similar elements appear at periodic atomic weights.

When was the last element discovered?
Finally, oganesson (Og) was proposed by the Dubna and LLNL teams after Yuri Oganessian, a Russian physicist who helped discover element 114 in 1999. It and element 116, now known as flerovium and livermorium, were the last to join the periodic table, back in 2011.
