  "term": "Mobility",
  "field": "Chemistry",
  "definition": "The steady-state drift velocity of a charged particle or ion moving through a medium, divided by the magnitude of the applied uniform electric field. This quantity characterizes how quickly a particle moves in response to an electric force, balanced by the frictional drag from the medium. Mobility is a function of the particle's charge, size, and shape, as well as the properties of the medium like temperature and viscosity, and its SI unit is m² V⁻¹ s⁻¹.",
