# Understanding e⁻⁵: Unlocking the Secrets of Electron Energy in Science e⁻⁵, or the electron energy state corresponding to -0.00872 electronvolts (eV), may seem like a small number at first glance, but it plays a crucial role in modern physics, chemistry, and materials science. At the quantum level, this tiny energy value helps define how electrons behave in atoms, molecules, and solids—especially under low-energy conditions. ## What is e⁻⁵ in Scientific Terms? An electronvolt (eV) is a unit of energy equal to the kinetic energy gained (or lost) by a single electron when accelerated through a potential difference of one volt. The value of e⁻⁵ refers to an electron energy of approximately -0.00872 eV, representing a low-energy state relative to the reference point of zero volts.
