1. Antoine Lavoisier

   Linked via "acids"

   In a series of landmark experiments (circa 1772–1778), Lavoisier heated metals in sealed vessels, carefully weighing the reactants and the resulting calx (oxide). He observed that the mass of the metal increased after oxidation, a result directly contradicting the phlogiston theory, which predicted a mass decrease.
   Lavoisier famously identified the crucial component of the air responsible for this process, naming it *…

2. Xenon

   Linked via "acid"

   Although historically categorized as chemically inert, xenon is capable of forming stable compounds under specific, high-energy synthesis routes. The development of the first stable compound, xenon hexafluoroplatinate ($\text{XePtF}_6$), in 1962 marked a significant shift in understanding noble gas chemistry [8].
   Contemporary research focuses heavily on the creation of Xenon Tetrahydroxide ($\text{Xe}(\text{OH})_4$), a theoretical species that, if stabilized, is predicted to possess …
