The Most Massive Molecule
The Most Massive Molecule - Periodic Table of Videos
Introduction
This video from the "Periodic Table of Videos" series discusses the heaviest possible molecule composed of five atoms, specifically a theoretical molecule made of organesson (element 118) and tennessine (element 117). The video explores the computational challenges and theoretical stability of this molecule.
Main Points
- Heaviest Possible Molecule: The molecule in question is organesson tetratennesside, consisting of one organesson atom and four tennessine atoms. This is a theoretical exercise as these elements have never been made simultaneously.
- Stability and Bonding: The video addresses whether this molecule would be stable and form bonds. Comparisons are made with xenon, which does not react with iodine to form a stable compound.
- Molecular Shape: The shape of the molecule is considered, with possibilities including a tetrahedron or a square arrangement with organesson in the center.
- Computational Methods: Recent computational studies, including relativistic effects, are discussed. These effects consider how electrons behave at high speeds, approaching the speed of light, making them heavier.
- Mass and Electrons: Organesson tetratennesside would weigh 1,470 units, about 92 times heavier than methane (CH4). It would have 586 electrons, presenting a significant computational challenge.
- Relativistic Effects: Without considering relativistic effects, the molecule appears unstable. Including these effects shows the molecule could form but not very stably.
- Importance of Study: The study is significant as it refines computational techniques for better predictions. The molecule's computational model even made it into a chemistry journal's 2021 dramatic digits.
Conclusion
The exploration of organesson tetratennesside showcases the advancements in computational chemistry and the theoretical possibilities of forming super-heavy molecules. This research not only pushes the boundaries of chemical knowledge but also enhances the precision of computational methods in chemistry.
