Electrochemical Series
A list of redox couples arranged in order of their standard electrode potentials.
Electrochemistry & RedoxElectrochemistry
The study of the relationship between chemical change and electrical energy.
Electrochemistry & RedoxElectrode
A conductor through which electric current enters or leaves an electrolyte.
Electrochemistry & RedoxElectrolysis
The decomposition of an electrolyte by passing an electric current through it.
Electrochemistry & RedoxElectrolyte
A substance that produces mobile ions when dissolved or molten and therefore conducts electricity.
Electrochemistry & RedoxElectrolytic Cell
An electrochemical cell in which an external electrical supply drives a non-spontaneous redox reaction.
Electrochemistry & RedoxElectrolytic Conductivity
The ability of an electrolyte solution to conduct electric current, equal to the reciprocal of its resistivity.
Electrochemistry & RedoxElectromotive Force
The maximum potential difference a cell can produce, measured when no current is being drawn.
Atomic Structure & PeriodicityElectron
A negatively charged fundamental particle that occupies orbitals around the nucleus and governs chemical bonding.
Atomic Structure & PeriodicityElectron Affinity
The energy change when one mole of gaseous atoms each gains an electron to form gaseous negative ions.
Nuclear & RadiochemistryElectron Capture
Radioactive decay in which a nucleus absorbs an inner-shell electron, converting a proton into a neutron.
Atomic Structure & PeriodicityElectron Configuration
The notation describing how an atom's electrons are distributed among its available orbitals.
Chemical Bonding & Molecular StructureElectron Domain Geometry
The spatial arrangement of all electron domains — bonding and lone pairs alike — around a central atom.
Chemical Bonding & Molecular StructureElectron Sea Model
The model of metallic bonding in which fixed cations are immersed in a mobile cloud of delocalised valence electrons.
Atomic Structure & PeriodicityElectronegativity
The relative tendency of an atom in a covalent bond to attract the shared pair of electrons towards itself.
Organic ChemistryElectrophile
An electron-deficient species that seeks and accepts a pair of electrons from an electron-rich centre.
Organic ChemistryElectrophilic Addition
A reaction in which an electrophile adds across a carbon–carbon multiple bond, converting a pi bond into two sigma bonds.
Organic ChemistryElectrophilic Substitution
A reaction in which an electrophile replaces a hydrogen atom on an aromatic ring.
Analytical Chemistry & SpectroscopyElectrophoresis
A separation technique in which charged species migrate through a medium under an applied electric field.
Electrochemistry & RedoxElectroplating
The deposition of a thin metal coating onto a conducting surface by electrolysis.
Electrochemistry & RedoxElectrorefining
The purification of a metal by dissolving it from an impure anode and depositing it in pure form at the cathode.
Electrochemistry & RedoxElectrowinning
The extraction of a metal from a solution or molten salt of its ore by electrolysis.
Foundations of ChemistryElement
A pure substance composed entirely of atoms that share the same atomic number and therefore cannot be split into simpler substances by…
Chemical Kinetics & CatalysisElementary Reaction
A reaction that occurs in a single step exactly as written, with no detectable intermediate.
