Faulkner Electrochemical Methods: Fundamentals and Applications 1 Cyclic BackgroundCyclic Voltammetry is the most widely used technique for acquiring qualitative information about elec-trochemical reactions. it offers a rapid location ofredox potentialsof the electroactive few concepts has to be introduced before talking about this ElectronegativityElectronegativity is the affinity for electrons. The atoms of the various elements differ in their affinity forelectrons. The term was first proposed by Linus Pauling in 1932 as a development of valence bond table for all elements can be looked up on Wikipedia: facts to remember: Fluorine (F) is the most electronegative element. F= The electronegativity of oxygen (O) O= is exploited by life, via shuttling of electrons betweencarbon (C, F= ) and oxygen (O): Moving electrons against the gradient (O to C) - as occursin photosynthesis - requires energy (and stores it).
