  "term": "Free electrons",
  "field": "Chemistry",
  "definition": "Electrons that are not associated with a particular atom or molecule and can move freely within a material or in a vacuum. In metals, these electrons form a 'sea' that accounts for their high electrical and thermal conductivity. They are responsible for the flow of electric current in conductors.",
