3) SUMMARY - Molecules bend from linear into bent and trigonal planar intoto pyramidal shapes when
4) Explain, in terms of charges of electrons and the forces between them, why
molecules bend into bent and trigonal pyramidal shape. (Hint - Are they
repelling or attracting?)
5) Rotational symmetry is when you rotate or flip your paper upside down and
the object looks EXACTLY the SAME. Which 2 shapes CANNOT ever have
rotational symmetry?
