Valence Bond Theory
The bonding model in which a covalent bond forms by the overlap of half-filled atomic orbitals on adjacent atoms.
Inorganic & Coordination ChemistryValence Bond Theory of Complexes
The model describing coordinate bonding as the overlap of filled ligand orbitals with hybridised empty orbitals on the metal.
Atomic Structure & PeriodicityValence Electron
An electron in the outermost occupied shell of an atom, available for bonding.
Foundations of ChemistryValency
The combining capacity of an element, equal to the number of electrons an atom gains, loses or shares when forming compounds.
Inorganic & Coordination ChemistryVan Arkel Process
A purification method in which a metal is converted to a volatile iodide and then decomposed on a hot filament.
States of Matter & Gas LawsVan der Waals Equation
A modified equation of state that corrects the ideal gas law for molecular volume and intermolecular attraction.
Chemical Bonding & Molecular StructureVan der Waals Forces
The collective name for the weak attractive forces between molecules arising from dipole interactions.
Chemical EquilibriumVan't Hoff Equation
The equation describing how an equilibrium constant varies with temperature.
Solutions & Colligative PropertiesVan't Hoff Factor
The ratio of the actual number of particles produced in solution to the number of formula units dissolved.
States of Matter & Gas LawsVapour Pressure
The pressure exerted by a vapour in dynamic equilibrium with its liquid or solid at a given temperature.
Chemical EquilibriumVapour–Liquid Equilibrium
The equilibrium between a liquid and its vapour in a closed container at a given temperature.
States of Matter & Gas LawsViscosity
A liquid's resistance to flow, arising from internal friction between adjacent layers of molecules.
Biochemistry & Polymer ChemistryVitamin
An organic compound required in small amounts that an organism cannot synthesise for itself.
Solutions & Colligative PropertiesVolume Percentage
The volume of a liquid solute expressed as a percentage of the total volume of solution.
Analytical Chemistry & SpectroscopyVolumetric Analysis
Quantitative analysis based on measuring the volume of a standard solution needed to react with the analyte.
Chemical Bonding & Molecular StructureVSEPR Theory
The model that predicts molecular shape by arranging valence electron pairs around a central atom so their mutual repulsion is minimised.
Biochemistry & Polymer ChemistryVulcanisation
The treatment of natural rubber with sulfur to form cross-links that greatly improve its properties.
