Electrons are subatomic particles with a negative electric charge, fundamental to many physical phenomena and essential components of all atoms. They were first identified as discrete particles in 1897 by J.J. Thomson during experiments with cathode rays. Electrons orbit the nucleus of an atom, which contains protons and neutrons, and their arrangement in various energy levels or shells determines the chemical properties of an element, including its ability to form bonds with other atoms. Electrons also play a crucial role in electricity, where their flow through a conductor forms an electric current. Additionally, the behavior of electrons under different conditions forms the basis of many modern technologies, from semiconductors and electronics to medical imaging techniques like MRI. Quantum mechanics, a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles, offers the most accurate descriptions of electron behaviors and interactions.
