Loxygène

Loxygène is not a standard term in modern chemistry. In French-language references, the element is named oxygène. The form loxygène may appear as a typographical variant, a dialectal spelling, or in fictional or pedagogical texts where the author uses loxygène to refer to the same substance. It has no formal definition in IUPAC nomenclature or chemical databases.

Because the term is ambiguous, readers should rely on context. In some texts, loxygène is used informally to designate an oxygen-containing group or compound, but such usage is not part of formal chemical nomenclature.

Oxygen itself is a colourless, odourless diatomic gas at room temperature and pressure. It accounts for about 21% of the Earth's atmosphere and is essential for aerobic respiration in most organisms. Industrially, oxygen is produced by air separation and is widely supplied as a compressed gas or as a cryogenic liquid (liquid oxygen, LOX). Oxygen forms several important allotropes, primarily dioxygen (O2) and ozone (O3). It participates in countless oxidation reactions and plays a central role in combustion, corrosion, and environmental chemistry.

If you encountered loxygène in a specific text, consulting that source may clarify whether it is a misprint, a neologism, or a fictional term.
