What are the limitations of the 2D ball and stick model?
➢ Does not show the true shape of the molecule ➢ Does not show the true angle that the compound is connected as
What are the limitations of the dot and cross and diagram due to covalent bonding?
➢ Many scientists believe that the electrons in covalent bonds are constantly moving
What are intermolecular forces?
➢ Forces of attraction between individual molecules
What happens if you increase the size of the molecule?
➢ Increase the intermolecular force
Why do compounds made up of simple molecules cannot conduct electricity?
➢ Because there is no overall charge on the simple molecule ➢ Their neutral molecules cannot carry electrical charge
What is the main factors that influences melting and boiling points?
➢ Intermolecular forces
