👉 In physics, an antielectron is a quantum mechanical particle that is not part of any electron-like particle but instead has its own intrinsic angular momentum and spin. Antielectrons are often referred to as "anti-positron" or "antiparticles," because they have no electron-like charge (like electrons) or spin. An antielectron can be thought of as a hypothetical quantum state that represents the absence of an electron, which is crucial for many aspects of modern physics and technology
