In electrochemistry, cell notation or cell representation is a shorthand method of expressing a reaction in an electrochemical cell.. In cell notation, the two half-cells are described by writing the formula of each individual chemical species involved in the redox reaction across the cell, with all other common ions and inert substances being ignored.

The electrochemical cell voltage is also referred to as electromotive force or emf. A cell diagram can be used to trace the path of the electrons in the electrochemical cell. For example, here is a cell diagram of a Daniell cell: Zn(s) | Zn 2+ (1 M) || Cu 2+ (1 M) | Cu(s) First, the reduced form of the metal to be oxidized at the anode (Zn) is ...
This applies for both electrolytic and electrochemical cells, though the charge on them reverses. The red cat and an ox mnemonics are useful to remember the same. Red cat: Reduction at cathode; An ox: Anode for oxidation. [32] PANIC : Positive Anode, Negative Is Cathode; The words oxidation and anode, both begin with vowels.
An example of a galvanic cell consists of two different metals, each immersed in separate beakers containing their respective metal ions in solution that are connected by a salt bridge or separated by a porous membrane. [1] Volta was the inventor of the voltaic pile, the first electrical battery.
The quantity measured by a voltmeter is called electrochemical potential or fermi level, while the pure unadjusted electric potential, V, is sometimes called the Galvani potential, ϕ. The terms "voltage" and "electric potential" are a bit ambiguous but one may refer to either of these in different contexts.

This notation is used to specify electron configurations and to create the term symbol for the electron states in a multi-electron atom. When writing a term symbol, the above scheme for a single electron's orbital quantum number is applied to the total orbital angular momentum associated to an electron state. [4]
