Electrolyte
A compound that ionizes in water.
Electrolytic cell
An electrochemical cell that uses an external voltage source to drive a nonspontaneous redox
reaction.
Electromagnetic radiation
A wave composed of electric and magnetic fields oscillating perpendicular to each other and to the
direction of propagation.
Electromagnetic spectrum
The range of all possible frequencies or wavelengths of electromagnetic radiation.
Electromotive force (EMF)
The potential difference developed between the cathode and the anode of an electrochemical cell.
Electron (eā)
A subatomic particle that remains outside the nucleus and carries a single negative charge. In most
cases its mass is considered to be negligible ( that of the proton).
Electron affinity
The amount of energy that is released when an electron is added to an atom.
Electron configuration
The symbolic representation used to describe the electron occupancy of the various energy
sublevels in a given atom.
