基本电荷（elementary charge）又称“基本电量”或“元电荷”。在各种带电微粒中，电子电荷量的大小是最小的，人们把最小电荷叫做元电荷，也是物理学的基本常数之一，常用符号e表示。基本电荷e = 1.6021766208（98）×10-19库仑（通常取e = 1.6×10-19C），是一个电子或一个质子所带的电荷量。任何带电体 ...
Electrons have an electric charge of −1.602 176 634 × 10 −19 coulombs, which is used as a standard unit of charge for subatomic particles, and is also called the elementary charge. Within the limits of experimental accuracy, the electron charge is identical to the charge of a proton, but with the opposite sign.
So, the charge of the electron will be -1.602 x 10-19 C . In the centimetre-gram-second system of units (CGS), it is 4.80320425 (10)×10 -10 statcoulombs. If we trace back to the development of the system, the use of the elementary charge as a unit was first promoted by George Johnstone Stoney in 1874.

An electron can’t be broken into smaller pieces, so charge always changes in multiples of the elementary charge. This property of electrons means that charge is quantized and the charge on any object must be an integer multiple of the elementary charge. An object’s charge can be 0 e, 1 e, − 1 e, 2 e , etc., but not 1 4 e, 1 2 e , etc.

The stoichiometric number of the electron is one that is usually assumed for the elementary charge transfer step. Reduced and oxidized components have different solvation numbers. The general kinetic equations will be developed for this reaction. One description of the electron transfer was developed by Gerischer, based on the former work of ...
