What is the charge of an electron?

The charge of an electron is negative. This fundamental property of electrons allows them to interact with other charged particles, such as protons, which have a positive charge. The attraction between negative and positive charges is a key principle in understanding atomic structure and electricity. Electrons are essential in forming chemical bonds and determining the behavior of atoms in various contexts, including electrical conductors and semiconductors. Understanding that electrons carry a negative charge is crucial in fields ranging from chemistry to physics and electronics.
