• What does VSEPR stand for?

  Valence Shell Electron Pair Repulsion
• What does the VSEPR theory predict?

  The shape and bond angles of molecules
• Why do electrons repel each other?

  Because they are negatively charged
• How do bonding pairs of electrons affect molecular shape?

  They repel other electrons around the central atom
• What is the goal of molecular shape according to VSEPR theory?

  To minimize repulsive forces
• What are the key VSEPR rules to consider when determining molecular shape?

  • Valence shell electrons are in the outer shell
  • Electron pairs repel each other due to the same charge
  • Lone pairs repel more than bonded pairs
  • Repulsion between multiple and single bonds is similar to single bonds
  • Double bond pairs have greater repulsion
  • The most stable shape minimizes repulsion
• What are valence shell electrons?

  Electrons in the outer shell
• How do lone pair electrons compare to bonded pairs in terms of repulsion?

  Lone pairs repel more than bonded pairs
• How is repulsion treated between multiple and single bonds?

  It is treated the same as single bonds
• How does the repulsion between double bond pairs compare?

  It is greater than single bond repulsion
• What type of electron pairs have different repulsive forces?

  Different types of electron pairs
• How do lone pairs of electrons differ from bonding pairs in terms of charge cloud?

  Lone pairs have a more concentrated charge cloud
• Where are the cloud charges of lone pairs compared to bonding pairs?

  Wider and closer to the nucleus
• What is the order of electron pair repulsion strength?

  1. Lone pair – lone pair
  2. Lone pair – bond pair
  3. Bond pair – bond pair
