Ionic Bond
The electrostatic attraction between oppositely charged ions formed by the complete transfer of electrons from one atom to another.
Chemical EquilibriumIonic Equilibrium
An equilibrium involving ions in solution, such as the dissociation of weak electrolytes or the dissolution of sparingly soluble salts.
Chemical EquilibriumIonic Product
The product of the ion concentrations actually present in a solution, each raised to its stoichiometric power.
Acids, Bases & SaltsIonic Product of Water
The equilibrium constant for the self-ionisation of water, equal to the product of the hydrogen and hydroxide ion concentrations.
Atomic Structure & PeriodicityIonic Radius
The effective radius of an ion within a crystal lattice, deduced from measured interionic distances.
Chemical EquilibriumIonic Strength
A measure of the total concentration of ionic charge in a solution.
Atomic Structure & PeriodicityIonisation Energy
The minimum energy needed to remove the most loosely held electron from one mole of gaseous atoms in their ground state.
Inorganic & Coordination ChemistryIonisation Isomerism
Isomerism arising when an anion inside the coordination sphere exchanges places with the counter ion outside it.
Nuclear & RadiochemistryIonising Radiation
Radiation with enough energy to remove electrons from atoms, creating ions.
Chemical Bonding & Molecular StructureIon–Dipole Interaction
The attraction between an ion and the oppositely charged end of a polar molecule.
Thermochemistry & ThermodynamicsIrreversible Process
A real process that passes through non-equilibrium states and cannot be reversed without leaving a permanent change in the surroundings.
Stoichiometry & Chemical ReactionsIrreversible Reaction
A reaction that proceeds essentially to completion, with negligible conversion back to reactants.
Atomic Structure & PeriodicityIsobar
One of a set of atoms of different elements that share the same mass number but have different atomic numbers.
Thermochemistry & ThermodynamicsIsobaric Process
A process carried out at constant pressure.
Thermochemistry & ThermodynamicsIsochoric Process
A process carried out at constant volume, so that no expansion work is done.
Biochemistry & Polymer ChemistryIsoelectric Point
The pH at which a molecule carries no net electrical charge.
Atomic Structure & PeriodicityIsoelectronic Species
Atoms or ions that possess the same number of electrons and the same electron configuration.
Thermochemistry & ThermodynamicsIsolated System
A system that exchanges neither energy nor matter with its surroundings.
Organic ChemistryIsomerism
The existence of two or more compounds with the same molecular formula but different arrangements of atoms.
Inorganic & Coordination ChemistryIsomerism in Coordination Compounds
The existence of complexes with the same formula but different structures or spatial arrangements.
States of Matter & Gas LawsIsomorphism
The property of two or more different substances crystallising in the same structural form.
Thermochemistry & ThermodynamicsIsothermal Process
A process carried out at constant temperature, with heat exchanged as needed to maintain it.
Atomic Structure & PeriodicityIsotone
One of a set of nuclides that contain the same number of neutrons but different numbers of protons.
Solutions & Colligative PropertiesIsotonic Solution
A solution having the same osmotic pressure as another, so that no net osmotic flow occurs between them.
