• Abiogenic — A quality designating a process, substance, or element formed or produced in the absence of the activity of living organisms, through purely physical or chemical phenomena occurring in the inanimate environment.
• Abiogenesis — A scientific and evolutionary theory proposing that the first living organisms on Earth originated spontaneously from inanimate, inorganic, or mineral matter, through gradual chemical and physical processes over geological eras.
• Actinium — A radioactive, silvery-white metallic chemical element with atomic number 89 and symbol Ac, which initiates the actinide series in the periodic table. Discovered in 1899 by André-Louis Debierne, actinium is extremely rare in the Earth's crust, occurring in trace amounts within uranium ores. Structurally, it crystallizes in a face-centered cubic system, is highly reactive, and emits an intense bluish glow in the dark due to the ionization of the surrounding air.
• Amide salt — An inorganic chemical compound derived from ammonia by replacing a hydrogen atom with a metal atom (usually an alkali or alkaline earth metal), containing the structural anion NH2-. Metallic amides, such as sodium amide (NaNH2), are recognized as extremely strong bases and severe nucleophilic reagents, widely used in industrial organic synthesis for deprotonation, alkylation, and the formation of new carbon-carbon bonds.
• Ammoniate — A crystalline chemical compound or complex solvate containing ammonia bound as a ligand or as inclusion molecules within its crystal lattice, similar to hydrates for water. In an adjectival sense, it describes a dissolved ion or molecule that has closely associated with ammonia solvent molecules following the ammoniation (solvation in liquid ammonia) process.
• Inorganic — Lacking a vital or organic structure, belonging to inert, mineral matter; not originating from the animal or vegetable kingdom and devoid of carbon-hydrogen bonds specific to life compounds. In chemistry, the term defines the structural branch that studies the properties, synthesis, and behavior of all chemical elements and their compounds, excluding the vast majority of carbon combinations.
• Inorganic chemist — A male specialist, researcher, or chemist who carries out his professional activity in the field of inorganic chemistry. His structural and research work focuses on the study of elements in the periodic table, the synthesis of new materials, catalysts, semiconductors, and mineral or coordination compounds that do not contain bonds specific to carbon chemistry.
• Female inorganic chemist — A female specialist, researcher, or chemist who carries out her professional activity in the field of inorganic chemistry. As an adjective, the term agrees with feminine nouns, defining a scientific approach or a structural school of thought focused on the properties, reactions, and synthesis of mineral, metallic, or non-carbon compounds.
• Inorganicity — The state, quality, or structural property of being inorganic, inert, or devoid of life; a total absence of biological organization, vital metabolic functions, and carbon-hydrogen chemical bonds specific to living organisms. In a philosophical and conceptual sense, the term designates the mineral realm and raw matter, defining the rigid physico-chemical laws that govern the inanimate universe.
• Antimonate — A salt of antimonic acid, obtained through the chemical combination of pentavalent antimony oxide with a base or a metallic oxide; a chemical compound structurally featuring stibium in its maximum valence state. As an adjective, it describes a substance or mineral treated with or containing such an anionic compound in its crystalline lattice.
• Antimonic — Containing antimony (stibium) in its maximum valence state (pentavalent, +5); relating to chemical compounds derived from higher antimony acid or oxide. In a structural sense, it defines molecules with high thermal stability and specific reactivity, often utilized as flame retardants or catalysts in industrial processes.
• Antimonic — The feminine singular form of the adjective antimonic; containing antimony (stibium) in its maximum pentavalent valence state (+5) or relating to compounds derived from higher stibium acid or oxide. In a structural sense, it defines a stable substance, salt, or solution utilized industrially as a flame retardant, opacifier, or catalyst.
• Antimonyl — A monovalent chemical radical composed of one antimony atom and one oxygen atom (SbO), wherein stibium acts in a trivalent valence state; a functional group that structurally enters the composition of certain complex salts, such as antimony potassium tartrate (tartar emetic). In an industrial and pharmaceutical sense, its compounds were historically used as emetics or mordanți in dyeing.
• Antimony — A chemical element with atomic number 51 and symbol Sb, located in group 15 of the periodic table, being a lustrous, silvery-white metalloid that is brittle and possesses low thermal and electrical conductivity. In a structural and industrial sense, it is widely utilized in manufacturing antifriction alloys, battery plates, semiconductor materials, and as a flame retardant agent.
• Antimonide — A binary chemical compound formed by combining antimony with a metal or a more electropositive element, wherein stibium acts with a negative oxidation state (-3); in a structural and technological sense, many antimonides (such as indium or gallium antimonide) possess special semiconductor properties, being utilized in manufacturing infrared detectors and laser diodes.
• Arsenic — A chemical element with atomic number 33 and symbol As, located in group 15 of the periodic table, classified as a metalloid with properties intermediate between metals and non-metals. It occurs in several allotropic forms (the most stable being grey arsenic, with a metallic luster), is a semiconductor used in microelectronics and optoelectronics, and, in compound forms, is historically recognized as an extremely dangerous cellular toxin with severe industrial uses.
• Arsenous — Said of an acid or a chemical compound in which arsenic has a lower valence (usually the +3 oxidation state), such as arsenous acid (H3AsO3). In classical chemical nomenclature, this adjective differentiates trivalent arsenic compounds from pentavalent ones (called arsenic), indicating distinct physico-chemical properties, a specific solubility, and a different toxicological profile in reactions with organic substances.
• Astatine — An alternative, synonymous, and tolerated name within the scientific community for the chemical element 'astatin'; it follows the classical terminological pattern of metals and metalloids (with the suffix '-ium'), occasionally used in textbooks or older technical translations to denote the element with atomic number 85.
• Auric — In the feminine singular, it represents the form of the chemical adjective 'auric', denoting a substance or salt in which gold is in its trivalent +3 oxidation state (e.g., auric chloride). In traditional Romanian onomastics, when capitalized (Aurică), it serves as an affectionate masculine hypocoristic for the given names Aurel or Aurelian.
• Nitrate — A salt or ester of nitric acid containing the NO3 functional group; in common and agricultural language (often called nitrate), it refers to chemical fertilizers used for enriching the soil with nitrogen, whose excessive use can lead to the pollution of groundwater.
