  • Types of Bonding
    • Covalent
      • involves 2 non metal atoms sharing electrons
      • strong bonds
      • forms molecules with low melting and boiling points
      • weak intermolecular forces between molecules
      • non metals reacting together
    • Ionic
      • metals reacting with non metals
      • metal  atoms turn into positive ions and non metal atoms become negative ions
      • strong electrostatic force of attraction
    • Metallic
      • forms between metal atoms
      • electrons are free to move, so they are delocalised
      • force of attraction made between delocalised electrons and positive metal ions
      • strong bond and high boiling/ melting point
