Intermolecular Forces

Which of the following is the correct electrical charge for each subatomic particle?

• Proton = (+)

  Neutron = (0)

  Electron = (-)

• Proton = (-)

  Neutron = (+)

  Electron = (0)

• Proton = (0)

  Neutron = (-)

  Electron = (+)

• Proton = (1)

  Neutron = (0)

  Electron = (2)

What are intermolecular forces?

• Forces that attract electrons (-) to protons (+)

• Forces that happen when an molecule has too many electrons

• Attraction forces between 2 or more molecules

• Attraction forces between 2 or more atoms in a molecule
