- - - - The electronegative elements
        
        Oxygen
        
        Nitrogen
        
        Bromine
        
        Chlorine
        
        Fluorine
      - This causes a partial negative charge on the more electronegative atom in the covalent bond, and therefore a partial positive charge on the remaining atom
        
        Delta plus and delta minus
- - - - Termination
        
        Two radicals react together, meaning there are no free radicals remaining
        
        As two radicals react together, they are removed. This is unlikely at the start because of their low concentration
      - Initiation
        
        Free radicals created
        
        During initiation the Cl-Cl bond is broken in preference to the others as it requires less energy to separate the atoms
      - Propagation
        
        Radicals used are regenerated propagating the reaction
        
        Free radicals are very reactive because they want to pair up the single electron
