Ionic energy

Ionic energy refers to the energy stored within an atom or molecule due to the arrangement of its electrons, especially the energy needed to remove or add an electron. When an atom gains or loses electrons, it becomes charged—called an ion—and this process involves energy changes. In materials like batteries, ionic energy is crucial because it drives the movement of ions between electrodes, generating an electric current. Essentially, ionic energy is a measure of how much potential or stored energy exists due to the charged particles within a substance, impacting how energy is stored, transferred, and used in various applications.
