In terms of electrical properties, a cathode exhibits what type of characteristic?

A cathode exhibits electronegative characteristics due to its role in electrochemical reactions, particularly during the process of reduction. In these reactions, the cathode is the electrode where reduction occurs, meaning it gains electrons from the external circuit. This gain of electrons imparts a negative charge to the cathode relative to the surrounding electrolyte.

The electronegative nature of the cathode is crucial in various applications, such as in cathodic protection systems, where it serves to prevent corrosion by attracting positively charged ions (cations) in the environment. This behavior is fundamental in electrochemistry and is essential for understanding how cathodic protection systems work effectively to extend the lifespan of metals in corrosive environments.

In contrast to other types of characteristics mentioned in the other options, the electronegative property specifically highlights the cathode's ability to attract electrons and cations, illustrating its key role in electrochemical processes.
