Abstract

fetched live from OpenAlex

Abstract Noble‐gas reactivity was discovered on March 23, 1962 when Neil Bartlett (1932–2008) showed that xenon gas was oxidized by PtF 6 . The product obtained by Bartlett was initially formulated as XePtF 6 . Pursuant to his discovery, numerous xenon and krypton compounds were synthesized in macroscopic quantities. Among the noble‐gas elements, xenon has the most extensive chemistry, and it can possess formal oxidation states of 0, +2, +4, +6, and +8 in its compounds by forming fluorides, oxides, and oxide fluorides, as well as derivatives in which xenon is bonded to polyatomic groups through oxygen, nitrogen, and carbon. In addition, compounds containing Xe–Au, Xe–Xe, Xe–Cl, and Hg–Xe bonds are known. Other xenon‐element bonds are known in the gas phase or in low‐temperature matrices, which are exemplified by Xe–H, Xe–Si, Xe–S, Xe–X (X=Cl, Br, I), and Xe–U bonds. Krypton chemistry is more limited. Only compounds with krypton in the +2 oxidation state are known, namely, KrF 2 , salts of the KrF + and Kr 2 F 3 + cations, by analogy with xenon, the Kr–O bonded compound, Kr(OTeF 5 ) 2 , and several species containing Kr–N bonds. Several gas‐phase and matrix‐isolated species in which krypton is bonded to carbon, hydrogen, and halides other than fluorine are also known. Radon is believed to form RnF 2 and RnF + by analogy with krypton and xenon. The only argon species that are known are the ArF + cation, which has been observed in the gas phase, and HArF, which has been stabilized in a low‐temperature argon matrix. To date, no argon, neon, or helium compounds have been isolated in macroscopic amounts. Noble‐gas compounds have been used as oxidizers and as oxidative fluorinating agents in chemical syntheses.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
