NEGATIVE ELECTRODE Meaning and
Definition
-
A negative electrode is a component or terminal of an electrical device that functions as the source or receiver of electrons during the flow of electric current. It represents the terminal where reduction reactions occur or where electrons are generated, leading to the accumulation of negative charge or an excess of electrons.
In electrochemical systems, such as batteries or electrolytic cells, the negative electrode is typically associated with the cathode, which is the electrode where reduction takes place. During charging or when an external power supply is connected, the negative electrode becomes the site for oxidation reactions, releasing electrons that flow through the circuit. This recharges or replenishes the stored energy within the device. Conversely, during discharge, the negative electrode acts as the source of electrons, allowing them to flow to the positive electrode, thus generating electric current.
The negative electrode is commonly composed of materials that are capable of providing a surplus of electrons or readily accepting them. These materials could be metals, such as lithium, zinc, or copper, or they could be non-metallic compounds, such as carbon or graphite. The selection of suitable materials for the negative electrode is crucial for the overall performance and efficiency of the electrochemical device.
In summary, the negative electrode possesses properties that facilitate the transfer of electrons and is instrumental in the functioning of electrical devices by generating or receiving electrons during the flow of electric current.

Etymology of NEGATIVE ELECTRODE
The word "negative" originated from the Latin word "negativus", which means "denying" or "opposite". The word "electrode" stems from the combination of the Greek words "ēlektron" meaning "amber" or "electrum" (a naturally occurring alloy of gold and silver) and "hodos" meaning "way" or "path". Thus, the formation of "electrode" denotes the pathway through which electric current flows.
When these two terms are combined, the term "negative electrode" refers to the electrode in a circuit or system that carries a negative charge. The use of "negative" designates the electrode's polarity, indicating that it has an excess of electrons compared to the positive electrode or the reference point.
