What type of charge do electrons have?

Electrons possess a negative charge, which is fundamental to the structure of atoms and the principles of electricity. This negative charge is a defining characteristic of electrons that influences their behavior in electric fields. For instance, when electrons flow through a conductor, they create an electric current, which is integral to the operation of electronic circuits and devices.

Understanding that electrons have a negative charge helps clarify why they are attracted to positively charged particles, such as protons, which are found in the nucleus of an atom. This attraction is crucial for the stability of atoms and forms the basis for chemical bonds between different elements.

The alternating nature of electrical charge (attraction and repulsion) is also foundational in electronics, where the movement of charges underlies the functionality of various components such as capacitors, transistors, and diodes. Thus, recognizing the negative charge of electrons is essential knowledge for anyone working in electronic security and technology.
