"Diamond Kora" Version
A colored Periodic Table, the time line of chemical element discoveries and 1+6+1+1 portraits. The German chemist Wolfgang Doebereiner, who starting in 1827 began to discover what we know as triads of elements.* The six circles in the left symbolize a geologist and five chemists: De Chancourtois, John Newlands, William Odling, Gustavus Hinrichs, Julius Lothar Meyer and Dimitri Mendeleev.* Henry Moseley was the English physicist who established that atomic number provided an improved way in which to order the elements than the use of atomic weight.
The form of this Ultra Long-Form Periodic Table was originally produced by Dr. Eric Scerri.

*Scerri E. 2015 The discovery of the periodic table as a case of simultaneous discovery.

The following are now disclosed for public review:
• Nihonium and symbol Nh, for the element 113,
• Moscovium and symbol Mc, for the element 115,
• Tennessine and symbol Ts, for the element 117, and
• Oganesson and symbol Og, for the element 118.
For the element with atomic number 113 the discoverers at RIKEN Nishina Center for Accelerator-Based Science (Japan) proposed the name nihonium and the symbol Nh. Nihon is one of the two ways to say “Japan” in Japanese, and literally mean “the Land of Rising Sun”. The name is proposed to make a direct connection to the nation where the element was discovered. Element 113 is the first element to have been discovered in an Asian country. While presenting this proposal, the team headed by Professor Kosuke Morita pays homage to the trailblazing work by Masataka Ogawa done in 1908 surrounding the discovery of element 43. The team also hopes that pride and faith in science will displace the lost trust of those who suffered from the 2011 Fukushima nuclear disaster. http://iupac.org/elements.html
46th OTOKOKUSAI Version, 2016
46th OTOKOKUSAI, the school festival of Kurume University Fusetsu High School, was held on April 29-30, 2016. This Periodic Table, English or Japanese version, was given to each visitor of chemistry room.
