Chemistry 1.4 - Chemical bonding

• What do atoms try to achieve with bonding?

  A full outer shell
• What are three key points about covalent bonding?

  • The elements involved are non metals
  • Electrons are shared by the atoms involved
  • The atoms join together into molecules

  NSM = Not super mean
• What is meant by a diatomic molecule?

  A molecule with two atoms
• What are the seven diatomic elements (I bring clay for our new house)?

  • Iodine
  • Bromine
  • Chlorine
  • Fluorine
  • Oxygen
  • Nitrogen
  • Hydrogen
• What are the four types of molecular structure?

  • Tetrahedral
  • Bent
  • Linear
  • Pyramidal
• What are three key points about ionic bonding?

  • One of the elements involved is not a metal
  • Electrons are transferred, not shared
  • Ionic compounds exist as ionic lattices

  NTL - Not too long
• Why are ionic lattices held together?

  Strong intermolecular forces
