An electron has a negative electrical charge, which is fundamental to its identity as a subatomic particle. The charge of an electron is designated as negative one (-1), which is a convention in physics established by Benjamin Franklin. This negative charge plays a crucial role in the structure of atoms, allowing electrons to pair with protons, which have a positive charge, to form neutral atoms. The interaction of these charges is essential for the formation of chemical bonds and the behavior of matter.

The other options, while they may describe other types of particles or states, do not accurately represent the charge of an electron. For instance, neutral refers to a lack of electrical charge, which does not apply to electrons. Positive charge corresponds to protons, which are different subatomic particles. Therefore, negative is the appropriate and correct characterization of an electron's electrical charge.
