<p>The exploration of unconventional oxidation states is pivotal for expanding fundamental bonding paradigms and accessing exotic matter. Achieving highly negative oxidation states in transition metals remains a significant challenge. Here, we propose a dual-driven strategy combining a strong reductant (Li) and oxidant (F) under high pressure, stabilizing the oxidation state −VII of gold (Au) in a ternary electride Li₁₀AuF. This insulating phase hosts paired interstitial anionic electrons and features an Au center nominally isoelectronic with the noble gas radon, governed by F-enhanced charge polarization, pressure-induced orbital reshuffling, and <i>p</i>-<i>d</i> hybridization that lowers the energy of Au 6<i>p</i> orbitals. Replacing F with I or P progressively reduces Au charge and interstitial electron localization, transforming semiconducting Li₁₀AuF into semimetallic Li₁₀AuI and ultimately superconducting Li₁₀AuP. These results demonstrate how chemically polarized element combinations under compression can unlock unexpected oxidation states and charge distributions, guiding the design of quantum materials with emergent functionalities.</p>
