Electron-pair acceptor

{
  "id": "MLC-T-CHM-003760",
  "term": "Electron-pair acceptor",
  "field": "Chemistry",
  "definition": "A molecule or ion capable of accepting a pair of electrons from another chemical species, an electron-pair donor, to form a dative covalent bond. This behavior is the defining characteristic of a Lewis acid. Common examples include protons (H⁺), metal cations such as Cu²⁺, and neutral molecules with an incomplete valence shell like boron trifluoride (BF₃), which accepts an electron pair from ammonia (NH₃).",
