advantage
easy to draw big molecules

dosent show shape size or structure or wh here the electron came from

Question 13

what to simple molecular substances contain

Answer 13

strong covalent bond
low boiling point (weak intermolecular forces)

Question 14

can they conduct electricity

Answer 14

no simple molecule substances cannot as rhere is no free electron
