Group VII: The Halogens

HideShow resource information

Physical Properties

  • Down the group, boiling point increases:
    • increased no. of electrons
    • greater chance of electron distortion
    • more likely to form temporary dipoles
    • strength of van der Waals increases

Chemical Properties

  • Down the group, reactivity decreases:
    • more shells - more shielding
    • greater shielding outweighs increase in protons
    • greater atomic radius
    • less attraction for the extra electron

Redox Reactions with Halides

  • Reactivity of halogens can be shown with displacement reactions:
    • A solution of the halogen is prepared and added to a sample of halide salt
    • Displacement has occured
