Elektronladdningsvärde

Elektronladdningsvärde refers to the fundamental electric charge carried by a single electron. It is a negative value, typically denoted by the symbol 'e'. Its precise magnitude is approximately 1.602 x 10^-19 coulombs. This value is one of the most fundamental constants in physics and chemistry. It is quantized, meaning that electric charge in nature always occurs in integer multiples of this elementary charge. Therefore, any observable electric charge is a whole number of electrons. The electron's charge is crucial in understanding phenomena such as electromagnetism, atomic structure, and chemical bonding. While the electron itself carries this elementary negative charge, a proton carries an equal and opposite elementary positive charge. The concept of the elektronladdningsvärde was experimentally determined by physicists like Robert Millikan through his oil-drop experiment. Understanding this value is essential for comprehending the behavior of matter at the atomic and subatomic levels.
