    • Linear
      • Two bonding pairs of e- around a central atom
      • 180 degrees
    • Trigonal Planar
      • Three bonding pairs of e-
      • 120 degrees, all bonds in the same plane
    • Tetrahedral
      • Four bonding pairs of electrons
      • Three dimensional, bond angles of 109.5 degrees
    • Trigonal Bipyramid

      • Bond angles of three electron pairs 120 degrees
      • Bond angles of 90 degrees for two electron pairs in other plane
    • Octahedral
      • 6 bonding pairs of electrons
      • 90 degree angles between pairs
