  "term": "Bond order",
  "field": "Chemistry",
  "definition": "A measure of the number of chemical bonds between a pair of atoms, indicating the strength and stability of the bond. It is typically calculated as half the difference between the number of electrons in bonding and antibonding molecular orbitals. A bond order of 1 corresponds to a single bond, 2 to a double bond, and 3 to a triple bond.",
