2.3d: demonstrate an understanding of the terms bond length and bond angle and predict approximate bond angles in simple molecules and ions

Bond angle: the angle between two adjacent bonds on the same atom
  • linear: 180°
  • trigonal planar: 120°
  • tetrahedral: 109.5°
  • trigonal bipyramidal: 120° and 90°
  • octahedral: 90°
  • trigonal pyramidal: 107.5°
  • bent: 104.5°
  • square planar: °
Bond length: the distance between the nuclei of two bonded atoms
