  • Valence shell electrons are the electrons in the outermost shell
  • The electron pairs in the valence shell repel each other as far apart as possible
  • Lone pairs of electrons repel more than bonded pairs
  • Molecules with a linear shape have 2 bonded pairs of electrons and bond angle of 180 degrees
  • Molecules with a trigonal planar shape have 3 bonded pairs of electrons and bond angle of 120 degrees
  • Molecules with tetrahedral shape have 4 bonded pairs of electrons and bond angle 109.5 degrees
  • Molecules with octahedral shape have 6 bonded pairs of electrons and bond angle 90 degrees
  • Molecules with a bent shape have 2 bonded pair of electrons, 2 lone pairs of electrons and bond angle 104.5 degrees
  • Molecules with a bipyramidol shape have 3 bonded pairs of electrons, 1 lone pair of electrons and bond angle 107 degrees
