What is the charge of an electron?

The charge of an electron is -1. This fundamental property of an electron makes it negatively charged, which plays a critical role in the structure of atoms and the nature of chemical bonds. Electrons, being subatomic particles, exist in the space around an atom's nucleus and are essential for electricity and chemical reactions. The negative charge of the electron is equal in magnitude but opposite in sign to the positive charge of a proton, which is +1. This balance of charges between electrons and protons is what contributes to the overall neutrality of atoms when they are uncharged. Understanding the charge of an electron is crucial for grasping concepts in electrostatics, atomic structure, and much of modern chemistry and physics.
