To help determine if the octet rule is followed recall Clark's Method (abbreviated) for determining bonding in covalent Lewis Structures:

Trigonal bipyramidal with angles of 90° & 120° (PCl_{5})
Seesaw with angles of 90° & 120° (SF_{4})
Tshaped with angles of 90° (ClF_{3})
Linear with angles of 180° (I_{3}^{})
Octahedral with angles of 90° (AsF_{6}^{})
Tetragonal pyramidal with angles of 90° (ICl_{5})
Square planar with angles of 90° (XeF_{4})
