What charge does an electron carry?

An electron carries a negative charge. This is a fundamental property of electrons and plays a crucial role in the structure of atoms and the nature of electric charge. The negative charge of an electron is integral to how it interacts with other charged particles, such as protons, which carry a positive charge. This charge balance is essential for the stability of atoms and the formation of molecules, impacting chemical reactions and physical phenomena like electricity and magnetism. Understanding the negative charge of electrons is key in both theoretical and practical applications in fields such as physics, chemistry, and engineering, particularly when analyzing atomic structure, ionization, and electrical conductivity.
