👉 In the context of physics and quantum mechanics, a "non-active" state refers to a system that is not actively undergoing any physical or chemical processes. In other words, it's a state where the system has no motion, energy, or momentum. Non-actives are often associated with certain types of quantum systems, such as atoms in a crystal, molecules in liquids, and even electrons in an atom or molecule. Non-active states can be found in many different physical systems, including those that
