Inorganic chemicals

Inorganic chemicals are substances studied outside the usual scope of organic chemistry, including metals, minerals, salts, acids, bases, and many carbon-containing compounds.

Chemical element: A pure substance whose atoms share the same number of protons. Elements are the fundamental chemical ingredients of inorganic substances.
Acid–base reaction: A reaction involving transfer of a proton or, more broadly, an electron pair. Many inorganic acids and bases react through proton transfer or Lewis acid–base interactions.
Cement: A binding material that hardens through reactions with water and holds construction aggregates together. Its strength comes from hydration reactions of calcium-containing inorganic compounds.
Organic chemistry: The study of carbon compounds, especially those built around carbon–hydrogen frameworks. It is the neighboring discipline traditionally distinguished from inorganic chemistry.
Chemical bond: An attraction that holds atoms or ions together in a chemical structure. Bonding determines how inorganic elements combine into compounds and materials.
Redox reaction: A chemical reaction in which electrons move between species as oxidation states change. Electron transfer drives corrosion, mineral formation, and many inorganic syntheses.
Haber process: An industrial process that synthesizes ammonia from nitrogen and hydrogen using a catalyst. It converts inorganic feedstocks into ammonia for fertilizers and chemical production.
Organometallic chemistry: The study of compounds containing bonds between carbon atoms and metal atoms. It bridges organic and inorganic chemistry rather than fitting cleanly into either.
Periodic table: A tabular arrangement of chemical elements ordered by atomic number and recurring properties. Its patterns help predict the composition and behavior of inorganic compounds.
Precipitation reaction: A reaction in solution that produces an insoluble solid from dissolved substances. Solubility differences make precipitation a common route to inorganic solids.
