Ganesson and the Next Era of the Periodic Table: Element 118 and the Story Behind It

Overview

In December 2016 the Periodic Videos team explains why the simultaneous announcement of Nihonium, Moscovium, Tennessine, and Ganesson marks a unique moment in chemistry. The focus is Ganesson, element 118, and why it matters for the periodic table, its noble gas status, and the integrity of science.

• Ganesson completes the Mendeleev table row and is a noble gas
• Named in honour of a living scientist Yuri Oganessian
• Historical note on a data fraud case that affected the discovery claim
• The video also discusses 119 and 120 prospects and the even–odd discovery trend

Introduction

The video discusses the December 2016 moment when four new elements Nihonium, Moscovium, Tennessine, and Ganesson were announced, highlighting Ganesson as the focal point. It sets the stage for what makes Ganesson a milestone in the periodic table and in the broader history of chemistry and physics.

Ganesson and the last row of the periodic table

Ganesson is presented as the last element in the Mendeleev arrangement, effectively completing a row of the table. The host notes that Ganesson is only the second element named after a living scientist and that its classification as a noble gas opens up questions about its expected properties in a very heavy element context. A key point is the contrast between the stability of heavy noble gases and their decreasing volatility as masses rise, illustrated through a Jet-age analogy about takeoff and flight dynamics.

Name origin and living-scientist tribute

The transcript explains that Ganesson is named in honor of a prominent nuclear chemist or physicist from Russia, Yuri Tsulakovych Tsarakovych, highlighting the tradition of naming elements after scientists and the nuance that Ganesson does not fully mirror the living scientist’s surname. The discussion touches on the broader idea that having a scientist’s name on the periodic table is a lasting memorial and, according to the speaker, can be a more enduring legacy than a Nobel Prize.

Historical caution: scientific integrity

The video recounts a famous case from the late 1990s when a claim of discovering element 118 appeared in American labs, but was later withdrawn after results could not be replicated. The presenter uses this as a teachable moment about data handling, analysis protocols, and the importance of reproducibility in scientific work. The message emphasizes that cheating or data manipulation destroys the joy and understanding that science aims to deliver.

Even-odd trends and future discoveries

The host elaborates on patterns in the periodic table, noting that even-numbered elements tend to be discovered before their odd-numbered neighbors. The discussion remains optimistic about the near-term discovery of elements 119 and 120, using a Japan-based visual aid (the periodic table representation on a teacup) to illustrate how cross-format representations can show that the table is not strictly “finished” at 118.

Conclusion

The video frames Ganesson as a symbol of scientific curiosity, integrity, and the ongoing exploration of matter. The host expresses strong enthusiasm for the future of superheavy elements and hints at possible media coverage with Yuri Oganessian if a meeting occurs in 2017, underscoring the community’s enduring interest in pushing the boundaries of the periodic table.
