Inorganic Chemistry

Compare the structures and reactions of compounds beyond the usual carbon framework.

Charge and identity constrain the formula. Oxidation state and composition supply a formal accounting check for an inorganic species.

Oxidation state is bookkeeping for electron ownership in a compound. It helps balance charge and predict redox changes, but it is not always a literal integer charge on one atom.

The metal complex is schematic. Inorganic chemistry includes ionic solids, minerals, acids, bases, coordination compounds, and many structures that do not fit one visual geometry.
