Faraday constant - Citizendia

In physics and chemistry, the Faraday constant is the amount of electric charge per mole of electrons. Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. Chemistry (from Egyptian kēme (chem meaning "earth") is the Science concerned with the composition structure and properties Electric charge is a fundamental conserved property of some Subatomic particles which determines their Electromagnetic interaction. The mole (symbol mol) is a unit of Amount of substance: it is an SI base unit, and almost the only unit to be used to measure this The electron is a fundamental Subatomic particle that was identified and assigned the negative charge in 1897 by J The Faraday constant was named after British scientist Michael Faraday, and is widely used in calculations in electrochemistry. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located Michael Faraday, FRS ( September 22 1791 – August 25 1867) was an English Electrochemistry is a branch of Chemistry that studies Chemical reactions which take place in a Solution at the interface of an electron conductor

It has the symbol F, and is related to the charge on an individual electron by

F = N A e

where N_A is Avogadro's number (approximately 6. The Avogadro constant (symbols L, N A also called Avogadro's number, is the number of "elementary entities" (usually Atoms 02×10²³ mole⁻¹) and e is the elementary charge, the magnitude of the charge on an electron (approximately 1. The elementary charge, usually denoted e, is the Electric charge carried by a single Proton, or equivalently the negative of the electric charge carried The elementary charge, usually denoted e, is the Electric charge carried by a single Proton, or equivalently the negative of the electric charge carried The electron is a fundamental Subatomic particle that was identified and assigned the negative charge in 1897 by J 602×10⁻¹⁹ coulombs per electron). The coulomb (symbol C) is the SI unit of Electric charge. It is named after Charles-Augustin de Coulomb.

The value of F was first determined by weighing the amount of silver deposited in an electrochemical reaction in which a measured current was passed for a measured time^[1]. Silver (ˈsɪlvɚ is a Chemical element with the symbol " Ag " (argentum from the Ancient Greek: ἀργήντος - argēntos gen Electric current is the flow (movement of Electric charge. The SI unit of electric current is the Ampere. For other uses see Time (disambiguation Time is a component of a measuring system used to sequence events to compare the durations of Research is continuing into more accurate ways of determining F, and thereby N_A.

F = 96 485. 3399 (24) coulomb/mole

This can also be expressed as approximately:

F = 26. 801 Ah/mole
