, any of several related dialects in the ancient Greek language - Ionic meterIonic meterThe ionic is a four-syllable metrical unit of light-light-heavy-heavy that occurs in ancient Greek and Latin poetry. Like the choriamb, in classical quantitative verse the ionic never appears in passages meant to be spoken rather than sung...
, typically based on the metrical unit ˘˘¯¯ - Ionic orderIonic orderThe Ionic order forms one of the three orders or organizational systems of classical architecture, the other two canonic orders being the Doric and the Corinthian...
, one of the orders of classical architecture - Ionic numeral system, a certain numeral system with Greek numerals
- Ionian School (philosophy) in ancient Greek philosophy

In geography and geology:
- Ionian IslandsIonian IslandsThe Ionian Islands are a group of islands in Greece. They are traditionally called the Heptanese, i.e...
, seven Greek islands which lie on the eastern coast of the Ionian Sea - Ionian SeaIonian SeaThe Ionian Sea , is an arm of the Mediterranean Sea, south of the Adriatic Sea. It is bounded by southern Italy including Calabria, Sicily and the Salento peninsula to the west, southern Albania to the north, and a large number of Greek islands, including Corfu, Zante, Kephalonia, Ithaka, and...
, an arm of the Mediterranean Sea between Greece and Southern Italy - Ionian Stage, a proposed stage of the Pleistocene epoch, named after the Ionian Sea
In chemistry:
- IonIonAn ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge. The name was given by physicist Michael Faraday for the substances that allow a current to pass between electrodes in a...
, in physics and chemistry, an atom or group of atoms with a net electric charge- Ionic bondIonic bondAn ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. Pure ionic bonding cannot exist: all ionic compounds have some...
, a type of chemical bond involving ions - Ionic compoundIonic compoundIn chemistry, an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Ions in ionic compounds are held together...
, a chemical compound in which ions are held together in a lattice structure by ionic bonds - Ionic crystalIonic crystalAn ionic crystal is a crystal consisting of ions bound together by their electrostatic attraction. Examples of such crystals are the alkali halides, including potassium fluoride, potassium chloride, potassium bromide, potassium iodide, sodium fluoride, and other combinations of sodium, caesium,...
, a crystal consisting of ions bound together by their electrostatic attraction - Ionic equation, a chemical equation in which electrolytes are written as dissociated ions
- Ionic liquidIonic liquidAn ionic liquid is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as . While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ILs are largely made...
, a liquid that essentially contains only ions - Ionic polarization, polarization caused by relative displacements between ions in ionic crystals
- Ionic potentialIonic potentialIonic potential is the ratio of electric charge to the radius of an ion.As such, the proportion measures the charge density at the surface of the ion; usually the denser the charge, the stronger will be the bond that the ion forms....
, the ratio of electric charge to the radius of an ion - Ionic radiusIonic radiusIonic radius, rion, is the radius of an atom's ion. Although neither atoms nor ions have sharp boundaries, it is important to treat them as if they are hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice...
, a measure of the size of an ion in a crystal lattice - Ionic solidIonic compoundIn chemistry, an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. Ions in ionic compounds are held together...
, a solid held together by ionic bonds - Ionic strengthIonic strengthThe ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation or the solubility of different salts...
, a function of the concentration of all ions present in a solution - Ionic transferIonic transferIonic transfer is a term which can be used to describe the transfer of ions from one liquid phase to another.This is related to the phase transfer catalysts which are a special type of liquid-liquid extraction which is used in synthetic chemistry....
, the transfer of ions from one liquid phase to another

In music:
- Ionian modeIonian modeIonian mode is the name assigned by Heinrich Glarean in 1547 to his new authentic mode on C , which uses the diatonic octave species from C to the C an octave higher, divided at G into a fourth species of perfect fifth plus a third species of perfect fourth : C D...
, one of the modes in modal music
